Pin Descriptions

PIN

NAME

FUNCTION

1

FB

Auxiliary voltage sense, output voltage protection and quasi resonant detection.

2

COMP

Voltage feedback pin. Connect a photo-coupler with it to close the control loop and

achieve the regulation.

3

CS

Current sense pin, connect it to sense the MOSFET current

4

GND

Ground

5

OUT

Gate drive output to drive the external MOSFET

6

VCC

Supply voltage pin

7

NC

Unconnected Pin

8

HV

Connect this pin to Line/ Neutral of AC main voltage through resistor to provide the

startup current for the controller.

When VCC voltage increase to trip the point of

UVLO(ON), this HV loop will be turned off to reduce the power loss on the startup

circuit.

An internal resistor divider between HV to GND pin will monitor AC line voltage to

activate Brown-in/out function control.
