BL8329— Features         Single Stage Flyback and PFC Controller with PSR for LED Lighting cost, and drives the converter in the quasi-resonant mode to achieve higher efficiency. It keeps the converter in constant on time operation to achieve high power factor. Primary Side Control and eliminates opto-coupler. Valley turn-on of the primary MOSFET to achieve low switching losses. 0.3V primary current sense reference voltage leads to a lower sense resistance thus a lower conduction loss. Low start-up current: 15uA (typical) Reliable LED open or short protection PF>0.90 with single-stage conversion. SOT23-6, SOP8 package available Meet the requirement of RoHS Pinout (top view) SOT23-6 Application  COMP 1 LED lighting BL8329 is a single stage flyback and PFC controller with primary side control for LED lighting, targeting at AC-DC LED lighting. BL8329 is a primary side controller without applying any secondary feedback circuit for low ISEN 3 8329S SSSS ZCS 2 General Description 8 GND NC 4 7 NC 6 VIN 5 DRV SOP8 PIN Description Pin No. Pin Name Pin Description 1(3) ISEN Current sense pin, connect the sense resistor (RCS) across this pin and GND 2(8) GND Ground pin 3(1) COMP 4(2) ZCS Inductor current zero-crossing detection pin. This pin receives the auxiliary winding voltage by a resister divider and detects the inductor current zero crossing point. This pin also provides over voltage protection and line regulation modification function simultaneously. If the voltage on this pin is above VZCS,OVP, the IC would enter over voltage protection mode. Good line regulation can be achieved by adjusting the upper resistor of the divider 5(6) VIN Power supply pin 6(5) DRV Gate driver pin. Connect to the gate of primary MOSFET. Loop compensation pin. Connect a RC network across this pin and ground to stabilize the control loop Note: The number outside brackets is SOT23-6 pin number. The number inside brackets is SOP8 pin number. http://www.belling.com.cn 1 V1.1  PDF
