current limit for the primary switch.

2

GND

Ground.

3

GATE

Gate Drive. Gate driver for the external MOSFET transistor.

4

VDD

Power Supply. This pin provides bias power for the IC during startup and steady state operation.

5

FB

Feedback Pin. Connect this pin to a resistor divider network from the auxiliary winding.

6

COMP

Compensation Pin.
