Datasheet AC/DC Drivers PWM Control type DC/DC converter IC BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ ●General The PWM type DC/DC converter (BM1Pxxx) for AC/DC provides an optimum system for all products that include an electrical outlet. BM1Pxxx supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM1Pxxx built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With switching MOSFET and current detection resistors as external devices, a higher degree of design freedom is achieved. Switching frequency adopts fixed system. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. At light load, the switching frequency is reduced and high efficiency is achieved. A frequency hopping function is also on chip, which contributes to low EMI. BM1Pxxx also has built-in function such as soft start, burst mode, over current limiter per cycle, VCC over voltage protection and over load protection. ●Features PWM frequency : 65kHz, 100kHz PWM current mode method Frequency Hopping function Burst operation / Frequency reduction function when load is light Built-in 650V start circuit VCC pin under voltage protection VCC pin over voltage protection CS pin Open protection CS pin Leading-Edge-Blanking function Per-cycle over current protection circuit Current protection with AC voltage compensation Soft start Secondary Over current protection circuit ●Package SOP-J8 ●Basic specifications Operating Power Supply Voltage Range: VCC 8.9V to 26.0V VH： to 600V Operating Current: Normal Mode：0.60mA (Typ) Burst Mode： 0.35mA (Typ) Oscillation Frequency: BM1P06xFJ：65kHz (Typ) BM1P10xFJ：100kHz (Typ) Operating Temperature: - 40deg. to +105deg. ●Application circuit 4.90mm×3.90mm ×1.65mm (Typ) (Typ) (Typ) Pitch 1.27mm (Typ) ●Applications AC adapters and household appliances (vacuum cleaners, humidifiers, air cleaners, air conditioners, IH cooking heaters, rice cookers, etc. ●Line-Up BM1P101FJ BM1P102FJ BM1P061FJ BM1P062FJ Frequency 100kHz 100kHz 65kHz 65kHz VCCOVP Auto Restart Latch Auto Restart Latch Figure 1．Application circuit ○Product structure：Silicon monolithic integrated circuit .www.rohm.com © 2012 ROHM Co., Ltd.

See the sections below for detailed descriptions. Figure 7. Start sequences Timing Chart A: Input voltage VH is applied B: This IC starts operating, when VCC pin voltage rises VCC > VUVLO1 (Typ=13.5 V). Switching function starts when other protection functions are judged as normal. Then the VCC pin voltage drop because of consumption current of VCC pin. In the case of VCC < VCHG1 (Typ=8.7V), the starting circuit operates and changes the VCC pin. The charging continue until the VCC become less than VCHG1 (Typ=13.0V). C: With the soft start function, the value of CS pin has to be restricted to prevent any excessive rise in voltage or current. D: When the switching operation starts, VOUT rises. It is necessary that the output voltage is be set to be rated voltage until TFOLP2 (Typ=32ms) after starting switching. E: At the light load condition, the burst operation starts in order to restrain power consumption. F: The FB pin becomes more than VFOLP1A because the output voltage lowers at over load operation. G: When FB pin voltage keeps more than VFOLP1A for TFOLP2 (Typ=32ms), the overload protection function is triggered and switching stops. If the FB pin voltage becomes less than VFOLP1B, the IC’s internal timer is reset. H : If the VCC voltage drops to VCHG1 (Typ=8.7V) or below, the starting circuit operates and VCC starts to charge. I: If the VCC voltage raises to VCHG2 (Typ=13.0V) or above, the charging by the starting circuits stops. J: Same as F K: Same as G www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

VCC UVLO and VCC OVP functions are the functions that prevent MOSFET for switching from destroying when the VCC voltage drops or rises. VCC charge function stabilizes the secondary output voltage to be charged from the high voltage line by start circuit at dropping the VCC voltage. (3-1) VCC UVLO ／ VCC OVP function VCCUVLO is auto recovery comparator that has the voltage hysteresis. BM1Pxx1 series has auto recovery type VCCOVP. BM1Pxx2 series has latch type VCCOVP. It is necessary that VCC is less than VLATCH (Typ=7.7V) to reset the latch after detecting latch operation by VCC OVP. Refer to the operation figure-8. This function has a built-in mask time TLATCH（typ=100us）. This detects it if the condition that VCC pin is more than VOVP1 (Typ=27.5V) continues for TLATCH (Typ=100us). By this function, it masks the surge occurs at the pins.

An internal oscillator fixes switching frequency. BM1Pxxx is integrated the hopping function of the switching frequency which changes the switching frequency to fluctuate as shown in Figure 10. The fluctuation cycle is 125 Hz typ. Figure 10-1. hopping function (BM1P06x series) Figure 10-2. hopping function (BM1P10x series) Max duty cycle is fixed as 75% (Typ) and MIN pulse width is fixed as 400 ns (Typ). With the current mode control, when the duty cycle exceeds 50%, sub harmonic oscillation may occur. As a countermeasure to this, BM1Pxxx has a built-in slope compensation circuits. BM1Pxxx has a built-in the burst mode circuit and the frequency reduction circuit to achieve low power consumption, at a light load. The FB pin is pull up by RFB (Typ=30 kΩ). The FB pin voltage is changed by secondary output voltage (secondary load power). By monitoring the FB pin voltage, the burst mode operation and the frequency detection is operated. Figure 11 shows the FB voltage, the switching frequency and the DC/DC operation ・mode1: the burst operation ・mode2: the frequency reduction operation. (reduce the max frequency) ・mode3: the fixed frequency operation.(operate at the max frequency) ・mode4: the over load operation.(detect the over load state and stop the pulse operation) Figure-11-1.

If the CS pin is exceeds a certain voltage, the switching is stopped. It also has built-in the AC voltage compensation function. This is the function which compensates a dependence of over current limiter value by AC voltage increasing over current limiter levels with time. Shown in figure-12, 13, 14. Figure 12. No AC voltage compensation function Figure 13.buit-in AC compensation voltage The primary peak current is decided as the formula below. The primary peak current: Ipeak = Vcs/Rs + Vdc/Lp*Tdelay Vcs ：the over current limiter voltage Rs ：the current detection resistance Vdc ：the input DC voltage Lp ：the Primary inductance Tdelay：the delay time after the detection of the over current limiter Figure 14. Over current limiter voltage （6）L.E.B period When the driver MOSFET is turned ON, a surge current occurs at capacitor components and the drive current. Therefore, because of rising the CS pin voltage temporarily, the detection errors may occur in the over current limiter circuit. To prevent this detection errors, this IC has a internal L.E.B function (Leading Edge Blanking function) that masks CS voltage for 250n sec after the OUT pin switches from Low to High. This L.E.B function reduces CS pin noise filter for the noise that occurs when the OUT pin switches from low to high. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

To prevent this damage, BM1Pxxx has a built-in the OPEN protection circuit（auto recovery protection）. (8) Output over load protection function （FB OLP Comparator） The output overload protection is the function that monitors the secondary output load status at the FB pin and stops a switching when an overload occurs. At an overload condition, the output voltage is dropped and the current can’t flow at the photo coupler, so the FB pin voltage is rised. If the condition When the status that the FB pin voltage is more than VFOLP1A (Typ=2.8V) continues for TFOLP2 (Typ=32ms), it is judged as an overload and stops switching. If the FB voltage drops from VFOLP1A (Typ=2.8V) to VFOLP1B (Typ=2.6V) within TFOLP2 (Typ=32ms), the time of over load protection is reset. The IC operates switching during TFOLP2 (Typ=32ms). At start-up, so the FB voltage is pulled up to the IC’s internal voltage that the operation starts from VFOLP1A (Typ=2.8V) or above. Therefore, at startup the FB voltage must be set to V FOLP1B (2.6 Vtyp) or below during T FOLP1 (32 ms typ), and the secondary output voltage’s start time must be set within T FOLP2 (32 ms typ) following startup of the IC. Recovery that once FBOLP is detected is after T FOLP2 (Typ=512ms). Figure 15. Over load protection (Auto recovery) A: The FBOLP comparator detects over load because the FB voltage is more than VFOLP1A. B: If the states of A continues for TFOLP2 (Typ=32ms), it is judged as an overload and stops switching. C: After the switching stops for the over load protection function, if the VCC pin voltage drops and the VCC pin voltage become less than VCHG and the VCC charge function operates so the VCC pin voltage rises. D: VCC charge function stops when VCC pin voltage becomes more than VCHG2. E: If it is passed TOLPST （typ =512ms） from B point, switching function starts on soft start. F: If the over load condition lasts, the condition that the FB pin voltage is more than VFOLP1A, too. And if it passed TFOLP2 (Typ=32ms), the switching is stopped. G: While the switching stops, if VCC pin voltage drops to VCHG1 or below, VCC charge function operates and VCC pin voltage rises. H: If VCC pin voltage exceeds VCHG2 by the VCC charge function, VCC charge function operation stops www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

It set the OUT pin high voltage to VOUTH（Typ=12.5V）. It prevents MOSFET gate form damage of VCC pin (6pin) voltage. (Shown in Figure16) Figure 16. OUT pin （5pin） Block Diagram (10) ACMONI Function Brownout function is built inside BM1PXXX. Brownout function means that DC/DC action will stop when input AC voltage is low. Application example is shown in Figure 17. Input voltage is divided by resistance and is input into ACMONI terminal. If the voltage of ACMONI terminal exceeds VACMONI1 (Typ=1.0V), the circuit detects normal status and start to execute DC/DC action. After DC/DC action and voltage of ACMONI terminal is lower than VACMONI2 (Typ=0.7V), TACMONI (Typ=256ms) later, DC/DC action becomes OFF. Figure 17.

TSZ22111・15・001 16/19 TSZ02201-0F2F0A200090-1-1 15.Oct.2015.Rev.005 BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ Datasheet ● Use-related cautions (1) Absolute maximum ratings Damage may occur if the absolute maximum ratings such as for applied voltage or operating temperature range are exceeded, and since the type of damage (short, open circuit, etc.) cannot be determined, in cases where a particular mode that may exceed the absolute maximum ratings is considered, use of a physical safety measure such as a fuse should be investigated. (2) Power supply and ground lines In the board pattern design, power supply and ground lines should be routed so as to achieve low impedance. If there are multiple power supply and ground lines, be careful with regard to interference caused by common impedance in the routing pattern. With regard to ground lines in particular, be careful regarding the separation of large current routes and small signal routes, including the external circuits. Also, with regard to all of the LSI’s power supply pins, in addition to inserting capacitors between the power supply and ground pins, when using capacitors there can be problems such as capacitance losses at low temperature, so check thoroughly as to whether there are any problems with the characteristics of the capacitor to be used before determining constants. (3) Ground potential The ground pin’s potential should be set to the minimum potential in relation to the operation mode. (4) Pin shorting and attachment errors When attaching ICs to the set board, be careful to avoid errors in the IC’s orientation or position. If such attachment errors occur, the IC may become damaged. Also, damage may occur if foreign matter gets between pins, between a pin and a power supply line, or between ground lines. (5) Operation in strong magnetic fields Note with caution that these products may become damaged when used in a strong magnetic field. (6) Input pins In IC structures, parasitic elements are inevitably formed according to the relation to potential. When parasitic elements are active, they can interfere with circuit operations, can cause operation faults, and can even result in damage. Accordingly, be careful to avoid use methods that enable parasitic elements to become active, such as when a voltage that is lower than the ground voltage is applied to an input pin. Also, do not apply voltage to an input pin when there is no power supply voltage being applied to the IC. In fact, even if a power supply voltage is being applied, the voltage applied 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, consider possible reduction to below the nominal capacitance due to current bias and capacitance fluctuation due to temperature and the like before determining constants. (8) Thermal design The thermal design should fully consider allowable dissipation (Pd) under actual use conditions. Also, use these products within ranges that do not put output Tr beyond the rated voltage and ASO. (9) Rush current In a CMOS IC, momentary rush current may 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 Test pins and unused pins should be handled so as not to cause problems in actual use conditions, according to the descriptions in the function manual, application notes, etc. Contact us regarding pins that are not described. (11) Document contents Documents such as application notes are design documents used when designing applications, and as such their contents are not guaranteed. Before finalizing an application, perform a thorough study and evaluation, including for external parts. Status of this document The Japanese version of this document is formal specification.
