EV4030A-S-00B – HIGH LINE VOLTAGE, 16W PSR WITH PFC DIMMABLE LED DRIVER

CIRCUIT DESCRIPTION The EV4030A-S-00B is configured in a singlestage Flyback topology, it uses primary-sidecontrol which can mostly simplify the schematic and get a cost effective BOM. It can also achieve high power factor and accurate LED current. F1, RV1, L1, L2, L3, R1, R14, R13, CX1, DB1, and C1 compose the input stage. F1 fuses the AC input to protect for the component failure or some excessive short events. RV1 is used for surge test. L1, L2, L3, R1, R14, CX1, R13 and C1 associated with CY1 form the EMI filter which can meet the standard EN55015. The diode rectifier DB1 rectifies the input line voltage. Small bulk CBB capacitor C1 is used for a low impedance path for the primary switching current, to maintain high power factor, the capacitance of C1 should be selected with low value. R3, R8, R5, R23, C4, C11, D1, D4, Q1, Q3 with R12 compose the damping circuit for reducing the inrush current at the dimmer turning on time. The circuit let the inrush current flow through R12 at first when triac dimmer turns on. Then Q1 turns on and shorts R12, this can save power from R12. Q3 is used to discharge C4 when the triac is off. D4 is used to clamp the gate voltage of Q1 to 15V. R4, R7, C3 are used as a bleeder circuit which keeping the triac current above the minimum holding current after triac turns on.

R11, D7, C10 and D10 are used to supply the power for MP4030A. A 47μF bulk capacitor C10 is selected to maintain the supply voltage. At start-up, C10 is first charged up through the external MOSFET Q2 and internal charging circuit, when the VCC voltage reaches 10V, the internal charging circuit stops charging and the control logic works. Then the power supply is taken over by the auxiliary winding through R11, D7. R6, C7, D6 and D5 are used for the gate drive of the external MOSFET Q2. R15, R16 are used to detect the auxiliary winding to get the transformer magnetizing current zero crossing signal for realizing the boundary conduction operation, and also monitor the output OVP condition. The OVP voltage is set by the divider ratio of R15, R16. R18, R20 are primary sensing resistors for primary side current control. The value of R18, R20 set the output LED current. C2, R2, R22, D3 are used to damp the leakage inductance energy so the drain voltage can be suppressed at a safe level. Diode D2 rectifies the secondary winding voltage and the capacitor C5, C6 are the output filter. The resistor R9 is placed as pre-load to limit the output voltage rise too high in open load condition.

R10, R17, C9 provide sine wave reference for the primary peak current to get an active PFC function. The divided voltage should be lower than the max voltage rating of MULT pin.

APPENDIX RIPPLE SUPPRESSOR (Innovative Proprietary) For dimming LED lighting application, a single stage PFC converter needs large output capacitor to reduce the ripple whose frequency is double of the Grid. And in deep dimming situation, the LED would shimmer caused by the dimming on duty which is not all the same in every line cycle. What’s more, the Grid has noise or inrush which would bring out shimmer even flicker. Figure 6 shows a ripple suppressor, which can shrink the LED current ripple obviously.

Drain current level can be selected as decuple as the LEDs’ current at least. About the RC filter, it can be selected by RC  50 / fLineCycle . Diode D can select 1N4148, and the Zener voltage of DZ is as small as possible when guarantee VD  VDZ  0.5  VCO _PP . Optional Protection Circuit In large output voltage or large LEDs current application, MOSFET M may be destroyed by over-voltage or over-current when LED+ shorted to LED- at working.

Figure 6: Ripple Suppressor

Figure 7: Gate-Source OVP Circuit

Principle: Shown in Figure 6, Resister R, capacitor C, and MOSFET M compose the ripple suppressor. Through the RC filter, C gets the mean value of the output voltage VCo to drive the MOSFET M. M works in variable resistance area. C’s voltage VC is steady makes the LEDs voltage is steady, so the LEDs current will be smooth. MOSFET M holds the ripple voltage vCo of the output. Diode D and Zener diode DZ are used to restrain the overshoot at start-up. In the start-up process, through D and DZ, C is charged up quickly to turn on M, so the LED current can be built quickly. When VC rising up to about the steady value, D and DZ turn off, and C combines R as the filter to get the mean voltage drop of VCo. The most important parameter of MOSFET M is the threshold voltage Vth which decides the power loss of the ripple suppressor. Lower Vth is better if the MOSFET can work in variable resistance area. The BV of the MOSFET can be selected as double as VCo and the Continues

Figure 7 shows GS over-voltage protection circuit. Zener diode DG and resistor RG are used to protect MOSFET M from GS over-voltage damaged. When LED+ shorted to LED- at normal operation, the voltage drop on capacitor C is high, and the voltage drop on Gate-Source is the same as capacitor C. The Zener diode DG limits the voltage VGS and RG limits the charging current to protect DG. RG also can limit the current of DZ at the moment when LED+ shorted to LED-. VDG should bigger than Vth. Drain-Source Over-voltage and Over-current Protection As Figure 8 shows, NPN transistor T, resistor RC and RE are set up to protect MOSFET M from over-current damaged when output short occurs at normal operation. When LED+ shorted to LED-, the voltage vDS of MOSFET is equal to the vCo which has a high surge caused by the parasitic parameter. Zener Dioder DDS protects MOSFET from over-voltage damaged. Transistor T is used
