Name Function
1 6 V
s
/ZCD Connected to the auxiliary winding; this pin senses the voltage output for the primary
regulation and detects the core reset event for the Quasi−Resonant mode of operation.
2 5 FB This pin connects to an optocoupler collector and adjusts the peak current setpoint.
3 4 CS This pin monitors the primary peak current.
4 3 DRV Controller switch driver.
5 2 GND Ground reference.
6 1 V
CC
This pin is connected to an external auxiliary voltage and supplies the controller.
7 − NC Not Connected for creepage distance between high and low Voltage pins
8 − HV Connected the high−voltage rail, this pin injects a constant current into the V
CC
capaci-
tor for starting−up the power supply.
