It also achieves high power factor and excellent TRIAC dimming performance. F1, RV1, L1, R7, C2, and BD1 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, R7 and C2 form an EMI filter. The diode rectifier BD1 rectifies the input line voltage. C7, L3 and C3 form a π structure EMI. R12, C8 are used as a bleeder circuit which keeping the TRIAC current above the minimum holding current after TRIAC turns on. F S P M O D T N E R3, R11 are sensing resistors for LED current control. The value of R3 and R11 set the output LED current. R T S I D E T U B I Diode D1 is the Buck fly-wheel diode, the inductor L2 and the capacitor C4 are the output filter. The resistor R6 is placed as a dummy load to consume the output power in open load condition. The diode D3 is used to prevent the output current flowing back to IC when input Sine voltage drops lower than output voltage. C T O A I R1 and R2 are used to monitor the output OVP condition. The OVP voltage is set by the divider ratio of R1 and R2. D I R8, R9, R10, R5, Q1 with C5 compose the active damping circuit. It helps to reduce the inrush current through dimmer at the moment dimmer turning on. The circuit let the inrush current flow through R5 at the moment TRIAC dimmer turning on. Then Q1 turns on and shorts R5, this saves power loss from R5. The R10 connected from bus provides a bias voltage for the gate driver of Q1, which also save power loss of Q1. N O R4, D2, C1 and C6 are used to supply the power for MP4068. At normal work, the power is charged by the internal high voltage regulator from HV pin. But in deep dimming condition, the power may not be enough supplied only by the high voltage regulator, the diode D2 connected to output will help maintain the power supply voltage.
