Pin Function Description

1

Drain

High voltage power SenseFET drain connection.

2

GND

This pin is the control ground and the SenseFET source.

3Vcc

This pin is the positive supply input. This pin provides internal operating

current for both start-up and steady-state operation.

4Vfb

This pin is internally connected to the inverting input of the PWM comparator.

The collector of an opto-coupler is typically tied to this pin. For stable

operation, a capacitor should be placed between this pin and GND. If the

voltage of this pin reaches 7.5V, the over load protection triggers resulting in

shutdown of the FPS.

5

Soft-start

This pin is for the soft start. Soft start time is programmed by a capacitor on

this pin.
