Datasheet Application Note AC/DC Drivers PWM Control IC BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ ● Overview The PWM control IC for AC/DC “BM1Pxxx” provides an optimized system for all applications that include an electrical outlet. A built-in 650V startup circuit contributes to lower power consumption, and both isolated and non-isolated configurations are supported, simplifying the design of various types of low-power converters. External switching MOSFET and current detection resistors provide greater design flexibility. The switching frequency is fixed. Since current mode control is used, a current limit is imposed in each cycle, ensuring superior performance in bandwidth and transient response. Frequency is reduced at light loads, for higher efficiency. A frequency hopping function is also built in, contributing to low EMI. Additional features include soft start and burst functions, a per-cycle overcurrent limiter, VCC overvoltage protection, overload protection, and other protection functions. ● Key Specifications Operating supply voltage range: Operating current: Oscillation frequency: Operating temperature range: ● Features PWM frequency: 65 kHz, 100 kHz PWM current mode Frequency hopping function Light load burst operation / Frequency reduction function 650V startup circuit VCC pin undervoltage protection VCC pin overvoltage protection CS pin open protection CS pin Leading-Edge-Blanking function Per-cycle overcurrent limiter function Overcurrent limiter with AC voltage compensation function Soft start function Secondary overcurrent protection circuit ● Package SOP-J8 VCC 8.9 V to 26.0 V VH: to 600 V Normal: 0.60 mA (Typ.)

The startup circuit operates only at startup. Current flow during operation is shown in Figure 5. After startup, the only power consumed is due to the idling current ISTART3 (10uA typ.). Ex.) When Vac=100V, startup power consumption is: PVH=100V*√2*10uA =1.41mW Ex.) When Vac=240V, startup power consumption is: PVH=240V*√2*10uA=3.38mW Startup time is determined based on VH pin inrush current and VCC pin capacitance. Startup time reference values are shown in Figure 6. For example, when Cvcc=10uF, startup takes about 0.07 seconds. When the VCC pin has been shorted to GND, the ISTART1 current in Figure 5 flows. When the VH pin has been shorted to GND, a large current flows to GND from the VH line. To prevent this, please insert resistor RVH (5 kΩ ~ 60 kΩ) to limit the current between the VH line and the IC’s VH pin. 2 When the VH pin is shorted, power equal to VH /RVH is applied to the resistor. Therefore, select a resistor size that is able to tolerate this amount of power. If one resistor is not enough to withstand the amount of power dissipation, two or more resistors can be connected in series. Figure 4.

VH Voltage ISTART2 VH input current ISTART1 ISTART3 VUVLO1 VCC(5pin) VSC Switing Set voltage Secondary output A B C D Figure 7. Operating Waveforms at Startup A: VH voltage is supplied when plugged into an outlet. Charging starts from the VH pin the VCC pin via the startup circuit. At that time, VCC < VSC (0.8V typ.), so the VH input current is limited to ISTART1 by the VCC pin short protection function. B: Since VCC voltage > VSC (0.8V typ.), VCC short protection is cancelled and current flows from the VH input. C: Since VCC voltage > VUVLO1 (13.5V typ.), the startup circuit is stopped and VH input current flow is only ISTART3 (10uA typ.). In addition, when switching starts, secondary output begins to increase, but since the secondary output is low, VCC pin voltage is reduced. The drop rate of VCC is determined by the capacitance of the VCC pin capacitor and the IC current consumption as well as the load current connected to the VCC pin. (V/t = Cvcc/Icc) D: Since the secondary output has risen to a constant voltage, voltage is applied from the auxiliary winding to the VCC pin, stabilizing the VCC voltage. www.rohm.com © 2012 ROHM Co., Ltd.

See below for detailed descriptions. Figure 8. Startup Sequence Time Chart A: Voltage is applied to the input voltage (VH) pin (Pin 8). At that time, the ACMONI pin (Pin 1) rises to VACMONI1 >1.0V. B: The VCC pin (Pin 6) voltage rises, and when VCC ＞ VUVLO1 (13.5V typ.) the IC begins to operate. When the protection functions (ACMONI,VCC, CS, FB pin, temperature) are determined to be normal, switching operation begins. At this time, the VCC pin (Pin 6) current consumption causes the VCC pin voltage to drop. When VCC < VCHG1 (8.7V typ.), the startuo circuit operates to prevent startup errors, and VCC is charged. After startup, charging continues until VCC > VCHG1 (13.0V typ.). Refer to item (1) regarding startup circuit operation. C: With the soft start function, excessive rises in voltage and current are prevented by adjusting the voltage level of the CS pin (Pin 3). During soft start, the IC changes the overcurrent detection voltage from VCC_SS1 to VCC_SS4 to prevent output voltage overshoot. VCC_SS1 is described in Table 2 below. Table 2 Overcurrent Detection Voltage at Startup Vlim1 Soft Start 0.10 V (12%) Start ~ 0.5 ms 0.5 ms ~1 ms 0.15 V (25%) 1 ms ~2 ms 0.20 V (50%) 2 ms ~ 4 ms 0.30 V (75%) 4 ms ~ 0.500 V (100%) D: When switching operation starts, the secondary output voltage VOUT rises. After switching has started, set the output voltage to within TFOLP2 (32ms typ.) to become the rated voltage. E: When there is a light load, burst operation suppresses power consumption. F: When there is an overload, the FB pin (Pin 2) voltage becomes greater than VFOLP1A in order to reduce the output voltage. G: If the FB pin (Pin 2) voltage exceeds VFOLP1A for longer than TFOLP2 (32ms typ.), the overload protection circuit stops the switching operation during the TOLPST period (512ms typ.). When the FB pin (Pin 2) voltage exceeds VFOLP1B, the IC’s internal timer TFOLP2 (32ms typ.) is reset. H: When the VCC voltage drops to VCC < VCHG1 (8.7V typ.), the startup circuit operates and VCC charging begins. I: When the VCC voltage increases to VCC> VCHG2 (13.0V typ.), the startup circuit stops charging VCC.

Heavy-Load Startup Waveforms (3) VCC Pin Protection Function This IC includes a VCC pin undervoltage protection function (UVLO), overvoltage protection function (OVP), as well as a VCC charge function that operates when the VCC voltage has dropped. The VCC UVLO and OVP functions prevent damage to the switching MOSFET due to insufficient/excessive VCC voltage. When the VCC voltage drops, the VCC charge function charges from a line with higher voltage than the start circuit and stabilizes secondary output. (3-1) VCC UVLO and OVP Functions VCC UVLO is an auto-recovery type comparator with voltage hysteresis. For VCC OVP, the BM1Pxx1 Series features an auto-recovery type comparator while the BM1Pxx2 Series utilizes a latch-type comparator. Latch release (reset) after latch operation detection by VCC OVP is triggered when VCC < VLATCH (7.7V typ.). This operation is shown in Figure 8. A mask time TLATCH (100us typ.) is built into VCC OVP. Detection is performed when the VCC pin (Pin 6) voltage continues to exceed VOVP1 (27.5V typ.) for TLATCH (100us typ.). This function masks surges and the like.

B: When the VCC pin (Pin 6) voltage > VUVLO1, the VCC UVLO function is canceled and DC/DC operation begins. C: When the VCC pin (Pin 6) voltage > VOVP, VCC OVP detects overvoltage in the IC. D: When the VCC pin (Pin 6) voltage > VOCP continues for TLATCH (100us typ.), switching is stopped by the VCC OVP function. (Latch mode) E: When the VCC pin (Pin 6) voltage < VCHG1, the VCC charge function operates and the VCC pin (Pin 6) voltage rises. F: When the VCC pin (pin 6) voltage > VCHG2, the VCC charge function is stopped. G: Same as E. H: Same as F. I: High voltage line VH is reduced. J: When VCC < VUVLO2, the VCC UVLO function operates. K: When VCC < VLATCH,, latch is cancelled. • VCC Pin Capacitance Value To ensure stable operation of the IC, please set the VCC pin capacitance value to 10uF or greater. If the capacitor at the VCC pin is too large, the response of the VCC pin to the secondary output will be delayed. In cases where the transformer has a low degree of coupling, a large surge can be generated at the VCC pin, which may damage the IC. In this case, insert a resistance of 10Ω to 100Ω on a bus between the diode and capacitor after the auxiliary winding. As for constants, perform a waveform evaluation of the VCC pin and determine values that will prevent any surges at the VCC pin from exceeding the absolute maximum rating. • VCC OVP Voltage Protection Settings for Increased Secondary Output The VCC pin voltage is determined by the secondary output and the transformer ratio (Np:Ns). Accordingly, when the secondary output has become large, protection is possible by VCC OVP. The VCC OVP protection settings are as follows. Vout Np Ns Nb Figure 9 VCC OVP Settings This is determined by VCC voltage = Vout x Nb/Ns. (Vout: Secondary output, Nb: Auxiliary winding turns, Ns: Secondary winding turns). When secondary output x 1.3 occurs and protection is desired, set the number of winding turns so that 1.3 x Vout x (Nb/Ns) ＞ VOVP1. For VCC OVP protection, since there is a TLATCH (100us typ.) blanking time, VCC OVP protection cannot be detected for instantaneous surges at the VCC pin. However, VCC OVP is detected when the VCC pin voltage has become higher than VOVP1 for over the TLATCH period, such as due to the effects of a low degree of transformer coupling, so an evaluation of the application should be performed before setting VCC OVP. www.rohm.com © 2012 ROHM Co., Ltd.

At that time, the VCC pin (Pin 6) is charged from the VH pin (Pin 8) via the IC. This operation prevents VCC startup errors. The VCC pin is charged, and charging is stopped when VCC pin exceeds VCHG2. This operation is shown in Figure 9. Figure 10. VCC Pin Charge Operation A: The VH pin (Pin 8) voltage rises and the VCC charge function starts charging the VCC pin (Pin 6). B: When the VCC pin (Pin 6) voltage > VUVLO1, the VCC UVLO function is cancelled, the VCC charge function is stopped, and DC/DC operation starts. C: At startup, the output voltage is low, so the VCC pin (Pin 6) voltage drops. D: When the VCC pin (Pin 6) voltage < VCHG1, the VCC charge function operates and the VCC pin (Pin 6) voltage increases. E: When the VCC pin (Pin 6) voltage > VCHG2, the VCC charge function is stopped. F: When the VCC pin (Pin 6) voltage < VCHG1, the VCC charge function operates and the VCC pin (Pin 6) voltage rises. G: When the VCC pin (Pin 6) voltage > VCHG2, the VCC charge function is stopped. H: Output voltage startup ends, and the VCC pin (Pin 6) is charged by the auxiliary windings to stabilize the VCC pin (Pin 6). www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

The brownout function stops switching operation when the input AC voltage drops. An application example is shown in Figure 11. The input voltage utilizes a resistance divider. When the ACMONI pin exceeds VACOMONI (1.0V typ.), the circuit detects normal status and switching operation starts. After switching operation, when the ACMONI pin drops below VACMONI (0.7V typ.), the IC’s internal timer begins to operate. When the ACMONI pin stays below VACMONI (0.7V typ.) for at least TACMONI1 (256ms typ), DC/DC operation is turned off. Therefore, even when AC voltage is interrupted, operation continues for a time equal to TACMONI1 (256ms typ.). RH RL Figure 11. Application Circuit The brownout setting can be set by connecting an external resistor to the ACMONI pin. The setting method is as follows. ○ When the peak value of the AC line exceeds VHstart you should start operation by calculating the following: *VACMONI1 = 1.0V VHstart = (RH + RL) / RL x VACMONI1 Set the RH and RL values according to this equation. At this time, the brownout end voltage VHend is determined as: VHend = (RH+RL) /RL x VACMONI2 *VACMONI1 = 0.7V *When not using the brownout function, set the voltage to between VACMONI (1.0V typ.) and 5.0V. Supply the voltage either externally or using a resistance divider from the VCC pin. Vout Np Ns Nb Figure 12.

Ip Figure 13. Block Diagram of Internal IC PWM Operation Figure 14. Basic PWM Operation A: A SET signal is output from the IC’s internal oscillator, and the MOSFET is turned ON. At this time, the capacitance between the MOSFET drain and source is discharged, and noise is generated at the CS pin. This noise is called the Leading Edge. This IC has a built-in filter for this noise. (See 6) As a result of this filter and the delay time, the minimum pulse width of the IC is 400ns (typ). Afterward, current flows to the MOSFET and a Vcs=Rs*Ip voltage is supplied to the CS pin. B: When the CS pin voltage rises above the FB pin voltage/Gain (4 typ.) or the overcurrent detection voltage Vcs, a RESET signal is output and OUT is turned off. C: There is a delay time Tondelay between time point B and actual turn-off. This time is the result of differences in maximum power that occur based on the AC voltage. This IC includes a function that suppresses these differences. (See 5-4)) D: The energy that accumulates in the transformer during Ton is discharged to the secondary side, and the drain voltage starts to oscillate freely based on the transformer Lp value and the MOSFET’s Cds (drain-source capacitance). E: Since the IC’s internal switching frequency is predetermined, a SET signal is output from the internal oscillator occurs for a set period starting from point A, and the MOSFET is turned on. www.rohm.com © 2012 ROHM Co., Ltd.

PWM Operation in the IC The PWM frequency is generated by the OSC block (internal oscillator) in Figure 15. This oscillator has a switching frequency hopping function and the switching frequency fluctuates as is shown in Figure 16. The fluctuation cycle is 125Hz. Due to the frequency hopping function, the frequency spectrum is dispersed and the frequency spectrum peak is reduced. This increases the margin for EMI testing. Figure 16-1. Frequency Hopping Function (BM1P06x Series) Figure 16-2. Frequency Hopping Function (BM1P10x Series) In Figure 16, the duty is calculated as Ton * Switching frequency * 100. The maximum duty value is Dmax (75% typ.). Since PWM current mode is being used, sub-harmonic oscillation may occur if the duty exceeds 50%. Therefore, 22mV/us slope compensation is built in as a countermeasure. To reduce power consumption during light loads, burst mode and frequency reduction circuits are included. These operations are illustrated in Figure17. As shown in this figure, the frequency fluctuates based on the FB voltage. If the FB voltage is within the range indicated in mode 2, switching loss is reduced by reducing the number of internal oscillations based on the FB voltage. www.rohm.com © 2012 ROHM Co., Ltd.

Fixed frequency operation (operates at maximum frequency.) Overload operation (overload condition is detected and pulse operation is stopped.) (5-3) Overcurrent Detection Operation RFB (30kΩ typ.) is used to pull up the FB pin in response to the internal power supply (4.0V). When the load of the secondary output voltage (secondary load power) changes, the photocoupler current changes, and the FB pin voltage also changes. The FB voltage VFB is determined by the following equation: FB Voltage = 4V - IFB. (IFB: Photocoupler Current) For example, when the load becomes heavier, the FB current is reduced and the FB voltage rises. When the load becomes lighter, the FB current increases and the FB voltage drops. In this way, secondary power is monitored by the FB pin. As the FB pin voltage is monitored, if the load becomes lighter (FB voltage drops), burst mode operation or frequency reduction operation is performed. Figure 18 shows the CS detection voltage with regard to FB voltage. ⊿CS/⊿FB Gain : 1/4 Figure 18 FB Voltage - CS Voltage Characteristics When the FB voltage is less than 2.0V or when the CS voltage exceeds the FB voltage/Gain (4 typ.), the MOSFET is turned off. (See time point C in Figure 14.) When the FB voltage exceeds 2.0V, the CS voltage = Vcs + Kcs*Ton. Kcs*Ton depends on AC voltage compensation. (See 5-4) Therefore, the peak current Ip is determined as Ip=Vcs1/Rs. The current value for the MOSFET should be set with sufficient margin, taking into account the Ip value obtained from this formula. 2 Maximum power is determined as Pmax = 1/2 x Lp x Ip x Fsw. (Lp: Primary inductance value, Ip: Primary peak current, Fsw: Switching frequency) Vcs1 is determined as Vcs1 = Vcs (0.4V typ.) + Kcs (typ.= 20) * Ton + Vdelay. Vdelay is the amount of CS voltage increase during the delay time Rondelay between B and C in Figure 14. This is calculated as Vdelay = Vin / Lp * Tondelay * Rs. www.rohm.com © 2012 ROHM Co., Ltd.

In the equation below, (A) and (B) are assigned values similar to those for AC 100V and AC 200V to perform compensation. Vcs1 = Vcs (0.4V typ.) + Kcs (typ.= 20) *Ton + Vdelay (A) (B) These operations are shown in Figures 19, 20, and 21. When there is no AC voltage compensation, the peak current becomes offset during the response time. 1 When there is no AC voltage compensation, the peak current becomes offset during the response time. Figure 19. 1 Without AC Voltage Compensation Function The overcurrent limiter level is changed over time to match the peak current. Figure 20. With AC Voltage Compensation Function Primary peak current during overload mode is defined as follows.

Blanking Time When the drive MOSFET is turned on, a surge current is generated at time point A as shown in Figure 14. At that time, the CS voltage (Pin 4) rises, which may cause detection errors in the overcurrent limiter circuit. To prevent this, the OUT pin in the IC is switched from low to high and the CS voltage (Pin 4) is masked for 250ns by the built-in L.E.B. (Leading Edge Blanking) function. This blanking function can reduce the CS pin noise filter for noise generated when switching the OUT pin from low to high. However, if the CS pin noise does not stay within this 250ns period, an RC filter should be applied to this pin, as is shown in Figure 22. At this time, a delay time occurs due to the RC filter when the CS pin is detected. Even if there is no filter, attaching an RCS is recommended as a countermeasure against surges. The recommended resistance for Rcs is 1 kΩ. When filtering is desired, adjust Ccs for this resistance. Figure22. CS Pin Peripheral Circuit (7) CS Pin Open Protection When the CS pin (Pin 4) becomes open, transient heat (due to noise, etc.) occurs in the IC, which may become damaged.

The output overload protection function stops switching operation when mode4 is in overload mode. During an overload condition, the output voltage drops and so current no longer flows to the photocoupler while the FB voltage (Pin 2) rises. When the FB voltage (Pin 2) exceeds VFOLP1A (2.8V typ.) continuously for TFOLP2 (64ms typ.), an overload condition is determined to have occurred and switching is stopped. After the FB pin (Pin 2) exceeds VFOLP1A (2.8V typ.), if the FB pin voltage drops below VFOLP1B (2.6V typ.) during the TFOLP2 (64ms typ.) period, the overload protection timer is reset. Switching operations are performed during the TFOLP2 (32ms typ.) period. At startup, the FB pin (Pin 2) voltage is pulled up by a resistance to the IC internal voltage, and operation starts when the voltage reaches VFOLP1A (2.8V typ.) or above. Therefore, the startup time of secondary output voltage at startup must be set so that the FB voltage (Pin 2) drops to VFOLP1B (2.6V typ.) or below within the TFOLP2 (64ms typ) period. Once FBOLP is detected, recovery occurs after the TFOLP2 (512ms typ.) period. Figure 24. Overload Protection (Auto-Recovery) A: Since FB > VFOLP1A, the FBOLP comparator detects an overload. B: When the condition at A continues for TFOLP2 (32ms typ.), switching is stopped by the overload protection function. C: While switching has been stopped by the overload protection, the VCC voltage (Pin 6) drops and when the voltage at the VCC pin (Pin 6) becomes less than VCHG, the VCC charge function operates to increase the VCC pin voltage. D: When the VCC charge function causes the VCC pin (Pin 6) voltage to rise above VCHG2, the VCC charge function is stopped. E: When the TOLPST (512ms typ.) period that starts from time point B elapses, switching is started via soft start operation. F: While an overload condition remains, FB continues to exceed VFOLP1A and switching is stopped when the period TFOLP2 (32ms) from time point E has elapsed. G: While switching is stopped, the VCC voltage (Pin 1) drops and when the VCC pin (Pin 6) voltage < VCHG1, the VCC charge function operates and the VCC pin voltage increases. H: When the VCC charge function causes the VCC pin (Pin 6) voltage to exceed VCHG2, the VCC charge function is stopped. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

The VCC pin (Pin 6) voltage is raised to prevent MOSFET gate damage. (Shown in Figure16.) Figure 25. OUT Pin (Pin 5) Schematic (9-2) OUT Pin Driver Circuit Figure 26. OUT Pin (Pin 5) Driver Circuit Switching noise generated when OUT is turned on or off may cause EMI-related problems. In such cases, the MOSFET turn-on and turn-off times must be delayed. However, delaying the turn off time will increase switching loss. Figure 26 shows a delay circuit for the OUT pin. In Figure 26, ① is effective for both turn-on and turn-off operation. ② shows a delay in turn-on only, while turn-off is accelerated. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

Board Layout Pattern · Notes ① The red lines shown in Figure 27 are large current pathways. They should be laid out as short and thick as possible to prevent ringing and loss. Also, any loops that occur in the red lines should be made as small as possible. ② The orange lines in the secondary side of Figure 27 should also be made as short and thick as the red lines and should be laid out with the smallest loops possible. ③ Be sure to ground the red, brown, blue, and green lines at a single point. ④ The green lines are pathways for surges on the secondary side to escape to the primary side. Therefore, since a large current may flow instantaneously, they should be laid out independently of the red and blue lines. ⑤ The blue lines are GND lines for IC control. Although they do not experience large current flow, they are susceptible to the effects of noise, so they should be laid out independently of the red lines, green lines, and brown lines. ⑥ The brown lines are current pathways for the VCC pin. Current flows through these lines during switching, so they should also be laid out independently. ⑦ Do not route any IC control lines directly under the transformer, since they may be affected by magnetic flux. www.rohm.com © 2012 ROHM Co., Ltd.

(The temperature shown below is guaranteed, so be sure to take margin into account.) 1. The ambient temperature Ta must be less than 85°C. 2. IC loss must be less than the power dissipation.

Since the type of damage (short/open circuit, etc.) cannot be determined, in cases where a special mode may conceivably exceed the absolute maximum ratings, please consider implementing physical safety measures such as fuses. (2) Power supply and ground lines In the board pattern design, route the power supply and ground lines to achieve low impedance. If there are multiple power supply and ground lines, be careful about interference due to common impedance in the wiring pattern. With regard to ground lines in particular, make sure to isolate large current and small signal routes, including the external circuits. Also, for all of the power supply pins in this IC, in addition to inserting capacitors between the power supply and ground pins, please thoroughly verify any problems associated with capacitor characteristics, such as capacitance loss at low temperatures, before determining constants. (3) Ground potential Please set the ground pin potential to the minimum potential for all operating modes. (4) Pin shorts and mounting errors When mounting the IC on a board, please pay attention to the orientation and direction of the IC and possible misalignment. Incorrect mounting may damage the IC. Damage may also occur due to short circuit if foreign material is introduced between IC pins, between a pin and the power supply, or between a pin and GND. (5) Operation in strong magnetic fields Please note that malfunction may occur if this product is used in a strong magnetic field. (6) Input pins In IC structures, parasitic elements are inevitably formed in relation to the potential. The operation of parasitic elements can interfere with circuit operation, leading to malfunction and even damage. Therefore, please be careful to avoid usage methods that enable parasitic elements to operate, such as by supplying a voltage lower than the ground voltage to the input pin. Also, do not apply voltage to an input pin when there is no power supply voltage being supplied to the IC. In fact, even if power supply voltage is being supplied, the voltage supplied to each input pin should be either below the power supply voltage or within the guaranteed values in the electrical characteristics. (7) External capacitors When a ceramic capacitor is used as an external capacitor, please consider the possible drop in nominal capacitance due to DC bias as well as capacitance fluctuation due to temperature and the like before determining constants. (8) Thermal design The thermal design should take into account the power dissipation (Pd) under actual conditions. Also, please ensure that the output transistor does not exceed the rated voltage or ASO. (9) Rush current In a CMOS IC, rush current may momentarily flow if the internal logic is undefined when the power supply is turned ON, so caution is needed with regard to the power supply coupling capacitance, the width of power supply and GND pattern wires, and how they are laid out. (10) Handling of test pins and unused pins As noted in the function manual, application notes, and other documents, test pins and unused pins should be handled so as not to cause problems under actual conditions. Please contact us regarding pins that are not otherwise described. (11) Document contents Documents such as application notes are design resources intended for use when designing applications, and as such their contents are not guaranteed. Therefore, before finalizing an application, please conduct a thorough study and evaluation, including of the external parts.
