Pin Descriptions

Pin

NAME

FUNCTION

1

INV

Output voltage feed back control

2

RAMP

Ramp generator, connecting a resistor to GND pin to set the saw tooth signal

3

COMP

Output of the error amplifier for voltage loop compensation to achieve stable

4

CS

This pin is the input of the zero current detection and over-current protection

comparator

5

OVP

The OVP pin is used to detect PFC output over-voltage when the INV pin

information is not correct

6

GND

Ground

7

OUT

Gate drive output to drive the external MOSFET

8

VCC

Supply voltage pin
