Pin Name

Pin Function

1

INV

Inverting input of the error amplifier. The output voltage of the boost PFC converter should be

resistively divided to 2.5V.

2

CT

The Ct pin sources a current to charge an external timing capacitor. The circuit controls the

The Ct pin discharge the external timing capacitor at the end of the on time.

3

COMP

This pin is the output of the transconductance error amplifier. Components for the

compensation should be connected between this pin and GND.

4

OVP

The OVP pin is used to detect PFC output over-voltage when the INV pin information is not

correct.

5

CS

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

6

GND

The GND pin is analog ground.

7

OUT

This pin is the gate drive output.

8

VCC

This is the IC supply pin.
