MB39C603 Phase Dimmable PSR LED Driver IC for LED Lighting MB39C603 is a Primary Side Regulation (PSR) LED driver IC for LED lighting. Using the information of the primary peak current and the transformer-energy-zero time, it is able to deliver a well regulated current to the secondary side without using an opto-coupler in an isolated flyback topology. Operating in critical conduction mode, a smaller transformer is required. In addition, MB39C603 has a built-in phase dimmable circuit and can constitute flicker less lighting systems for phase dimming with low-component count. It is most suitable for the general lighting applications, for example replacement of commercial and residential incandescent lamps.

Function Explanations 8.1 LED Current Control by PSR(Primary Side Regulation) MB39C603 regulates the average LED current (ILED) by feeding back the information based on Primary Winding peak current (IP_PEAK), Secondary Winding energy discharge time (TDIS) and switching period (TSW ). Figure 8-1 shows the operating waveform in steady state. IP is Primary Winding current and IS is Secondary Winding current. ILED as an average current of the Secondary Winding is described by the following equation. 𝐼𝐿𝐸𝐷 = 1 𝑇𝐷𝐼𝑆 ×𝐼 × 2 𝑆_𝑃𝐸𝐴𝐾 𝑇𝑆𝑊 Using IP_PEAK and the transformer Secondary to Primary turns ratio (NP/NS), Secondary Winding peak current (IS_PEAK) is described by the following equation. 𝐼𝑆_𝑃𝐸𝐴𝐾 = 𝑁𝑃 × 𝐼𝑃_𝑃𝐸𝐴𝐾 𝑁𝑆 Therefore, 𝐼𝐿𝐸𝐷 = 1 𝑁𝑃 𝑇𝐷𝐼𝑆 × × 𝐼𝑃_𝑃𝐸𝐴𝐾 × 2 𝑁𝑆 𝑇𝑆𝑊 MB39C603 detects TDIS by monitoring the TZE pin and IP_PEAK by monitoring the CS pin and then controls ILED. An internal Err Amp sinks gm current proportional to IP_PEAK from the COMP pin during TDIS period. In steady state, since the average of the gm current is equal to internal reference current (ISO), the voltage on the COMP pin (VCOMP) is nearly constant. 𝐼𝑃_𝑃𝐸𝐴𝐾 × 𝑅𝐶𝑆 × 𝑔𝑚 × 𝑇𝐷𝐼𝑆 = 𝐼𝑆𝑂 × 𝑇𝑆𝑊 In above equation, gm is transconductance of the Err Amp and RCS is a sense resistance. Eventually, ILED can be calculated by the following equation. 𝐼𝐿𝐸𝐷 = 1 𝑁𝑃 𝐼𝑆𝑂 1 × × × 2 𝑁𝑆 𝑔𝑚 𝑅𝐶𝑆 Figure 8-1 LED Current Control Waveform IP_PEAK System Power supply through Diode Bridge (VBULK) IP IS_PEAK IP LP VAUX MB39C603 ADJ ILED ILED IS TON VD VTZE TZE IS TSW DRV CS RCS TDIS CD TZE threshold VD (VAUX) 1/4 x TRING GND VTZE 1/4 x TRING Document Number: 002-08450 Rev.*A Page 10 of 32 MB39C603 8.2 PFC (Power Factor Correction) Function Switching on time (TON) is generated by comparing VCOMP with an internal sawtooth waveform (refer to Figure 3-1). Since VCOMP is slow varying with connecting an external capacitor (CCOMP) from the COMP pin to the GND pin, TON is nearly constant within an AC line cycle. In this state, IP_PEAK is nearly proportional to the AC line voltage (VBULK). It can bring the phase differences between the input voltage and the input current close to zero, so that high Power Factor can be achieved. 8.3 Phase Dimming Function MB39C603 is compatible with both leading-edge dimmers (TRIAC dimming) and trailing-edge dimmers. To realize the phase dimming, this device has two functions, dimmer conduction angle detect function for LED current control and TRIAC dimmer hold current control function. Figure 8-2 shows how MB39C603 detects the conduction angle. VBULK is scaled via a resistor divider connected to the VAC pin. The conduction angle is detected by monitoring the voltage on the VAC pin (VVAC). MB39C603 measures a half of power cycle period (Tpow) as duration between negative crossings of V VAC and a Phase Comp threshold voltage (VPHTH2). Dimmer-ON period (Tdim) is measured as duration between a positive crossing of V VAC and another Phase Comp threshold voltage (VPHTH1) and the following negative crossing. Conduction angle is defined as Tdim/Tpow × 180°. Figure 8-2 Conduction Angle Detection Waveform VBULK VVAC VPHTH1 VPHTH2 Phase Comp Tpow output Tdim Conduction angle = Tdim / Tpow × 180° MB39C603 regulates LED current by changing a reference of Err Amp as a function of the conduction angle. Table 8-1 shows ILED dimming ratio based on the conduction angle. In addition, the initial ILED ratio in Power–On state is 5%. Table 8-1 ILED Ratio Based on Conduction Angles Conduction Angle θ < 45deg 45deg ≤ θ < 90deg 90deg ≤ θ < 135deg 135deg ≤ θ Document Number: 002-08450 Rev.*A ILED Ratio [%] 5 (25/45) × θ -20 (70/45) × θ -110 100 Page 11 of 32 MB39C603 8.4 HOLD Current Control Function The hold current control function prevents LEDs from flickering caused by shortage of hold current. The hold current (IHOLD) is the minimum current required to flow through TRIAC dimmer in order to keep the TRIAC on (refer to Figure 8-3). In small conduction angle, since ILED can be low, AC/DC Converter current (IBULK) and TRIAC dimmer current (ITRIAC) are reduced. Once ITRIAC falls below IHOLD, TRIAC goes off and this results in LED flickering. MB39C603 controls ITRIAC larger than IHOLD by adding the current (IBIP) via a BIP transistor (M1) with sensing ITRIAC and keeps the TRIAC on. ITRIAC is sensed with a resistor (RS). A bypass diode (DBYPASS) is used to clamp the voltage between RS terminals (VRS) and prevent the voltage on the HOLDDET pin (VHOLDDET) from exceeding absolute maximum ratings. An offset resistor (ROFFSET) is used to add an offset voltage to VHOLDDET and prevent VHOLDDET from the above ratings. RS is set as the following equation. 𝑅𝑆 = 𝑅𝑂𝐹𝐹𝑆𝐸𝑇 × 𝐼𝐻𝑂𝐿𝐷𝐷𝐸𝑇 − 𝑉𝐻𝑂𝐿𝐷𝑇𝐻 𝐼𝑇𝑅𝐼𝐴𝐶𝑀𝐼𝑁 where IHOLDDET is the current of the HOLDDET pin, VHOLDTH is Hold Amp threshold voltage, and ITRIACMIN is minimum TRIAC current chosen by designers. ROFFSET is set as the following equation. 𝑅𝑂𝐹𝐹𝑆𝐸𝑇 > 𝑉𝐵𝑌𝑃𝐴𝑆𝑆𝑀𝐴𝑋 − 0.3𝑉 𝐼𝐻𝑂𝐿𝐷𝐷𝐸𝑇 where VBYPASSMAX is the maximum forward voltage of DBYPASS. Hold Amp is designed only for driving BIP transistors. Connecting a resistor (RBASE) between the HOLDCNT pin and M1 base terminal limits the maximum IBIP value and clamp the rush current at TRIAC dimmer-on timing.

After the UVLO is released, this device enables switching and is operating in a forced switching mode (TON = 1.5 µs, TOFF = 78 µs to 320 µs). When the voltage on the TZE pin reaches the Zero energy threshold voltage (VTZETH = 0.7V), MB39C603 enters normal operation mode. After the switching begins, the VDD pin is also charged from Auxiliary Winding through an external diode (DBIAS).(Figure 8-4 blue path) During non-conduction period VVDD is not supplied from VBULK or Auxiliary Winding. It is necessary to set an appropriate capacitor of the VDD pin in order to keep VVDD above the UVLO threshold voltage in this period. An external diode (D1) between BiasMOS and the VDD pin is used to prevent discharge from the VDD pin to VBULK at zero cross points of the AC line voltage.

Since any Secondary Winding current does not flow, ILED is supplied only from output capacitors and decreases gradually. VVDD also decreases because there is no current supply from both Auxiliary Winding and VBULK. When VVDD falls below the UVLO threshold voltage, MB39C603 shuts down. Figure 8-6 Power-Off Waveform AC line removed VBULK VDD UVLO Vth = 8V DRV Shutdown VLED 8.7 IP_PEAK Detection Function MB39C603 detects Primary Winding peak current (IP_PEAK) of Transformer. ILED is set by connecting a sense resistance (RCS) between the CS pin and the GND pin. Maximum IP_PEAK (IP_PEAKMAX) limited by Over Current Protection (OCP) can also be set with the resistance. Using the Secondary to Primary turns ratio (NP/NS) and ILED, RCS is set as the following equation (refer to 8.1). 𝑅𝐶𝑆 = 𝑁𝑃 0.132 × 𝑁𝑆 𝐼𝐿𝐸𝐷 In addition, using the OCP threshold voltage (VOCPTH) and RCS, IP_PEAKMAX is calculated with the following equation. 𝐼𝑃_𝑃𝐸𝐴𝐾𝑀𝐴𝑋 = 8.8 𝑉𝑂𝐶𝑃𝑇𝐻 𝑅𝐶𝑆 Zero Voltage Switching Function MB39C603 has built-in zero voltage switching function to minimize switching loss of the external switching MOSFET. This device detects a zero crossing point through a resistor divider connected from the TZE pin to Auxiliary Winding. A zero energy detection circuit detects a negative crossing point of the voltage on the TZE pin to Zero energy threshold voltage (V TZETL). On-timing of switching MOSFET is decided with waiting an adjustment time (tADJ) after the negative crossing occurs. tADJ is set by connecting an external resistance (RADJ) between the ADJ pin and the GND pin. Using Primary Winding inductance (LP) and the parasitic drain capacitor of switching MOSFET (CD), tADJ is calculated with the following equation. 𝑡𝐴𝐷𝐽 = 𝜋 𝐿𝑃 × 𝐶𝐷 2 Using tADJ, RADJ is set as the following equation. 𝑅𝐴𝐷𝐽 𝑘𝛺 = 0.0927 × 𝑡𝐴𝐷𝐽 𝑛𝑠 Document Number: 002-08450 Rev.*A Page 14 of 32 MB39C603 8.9 Protection Functions Under Voltage Lockout Protection (UVLO) The under voltage lockout protection (UVLO) prevents IC from a malfunction in the transient state during VVDD startup and a malfunction caused by a momentary drop of VVDD, and protects the system from destruction/deterioration. An UVLO comparator detects the voltage decrease below the UVLO threshold voltage on the VDD pin, and then the DRV pin is turned to “L” and the switching stops. MB39C603 automatically returns to normal operation mode when VVDD increases above the UVLO threshold voltage. Over Voltage Protection (OVP) The over voltage protection (OVP) protects Secondary side components from an excessive stress voltage. If the LED is disconnected, the output voltage of Secondary Winding rises up. The output overvoltage can be detected by monitoring the TZE pin. During Secondary Winding energy discharge time, VTZE is proportional to VAUX and the voltage of Secondary Winding (refer to 8.1). When VTZE rises higher than the OVP threshold voltage for 3 continues switching cycles, the DRV pin is turned to “L”, and the switching stops (latch off). When VVDD drops below the UVLO threshold voltage, the latch is removed. Over Current Protection (OCP) The over current protection (OCP) prevents inductor or transformer from saturation. The drain current of the external switching MOSFET is limited by OCP. When the voltage on the CS pin reaches the OCP threshold voltage, the DRV pin is turned to “L” and the switching cycle ends. After zero crossing is detected on the TZE pin again, the DRV pin is turned to “H” and the next switching cycle begins. Over Temperature Protection (OTP) The over temperature protection (OTP) protects IC from thermal destruction. When the junction temperature reaches +150°C, the DRV pin is turned to “L”, and the switching stops. It automatically returns to normal operation mode if the junction temperature falls back below +125°C.

Usage Precautions Do not configure the IC over the maximum ratings. If the IC is used over the maximum ratings, the LSI may be permanently damaged. It is preferable for the device to normally operate within the recommended usage conditions. Usage outside of these conditions can have an adverse effect on the reliability of the LSI. Use the device within the recommended operating conditions. The recommended values guarantee the normal LSI operation under the recommended operating conditions. The electrical ratings are guaranteed when the device is used within the recommended operating conditions and under the conditions stated for each item. Take appropriate measures against static electricity. Containers for semiconductor materials should have anti-static protection or be made of conductive material. After mounting, printed circuit boards should be stored and shipped in conductive bags or containers. Work platforms, tools, and instruments should be properly grounded. Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial between body and ground. Do not apply negative voltages. The use of negative voltages below - 0.3 V may make the parasitic transistor activated to the LSI, and can cause malfunctions. Document Number: 002-08450 Rev.*A Page 26 of 32 MB39C603 12.
