Pin Descriptions

Pin

NAME

FUNCTION

1

ZCD

Quasi resonance detector, which supports programmable phase

angel cut-off setting. This pin receives the auxiliary winding voltage

through a resister divider and detects the quasi resonance. It also

provides protection for over-voltage output.

2

COMP

Loop compensation pin, connect a capacitor with it to stabilize the

control loop.

3

CS

Current sense pin, connect it to sense the MOSFET current for CC

loop and OCP.

4

GND

Ground

5

OUT

Gate drive output to drive the external MOSFET

6

VCC

Power source VCC pin

7

NC

Not connected.

8

HV

Connect this pin to the positive of main bulk cap to provide the

startup current for controller and detects phase angle of TRIAC.
