PIN NAME

DESCRIPTION

1

CS

Current Sense Pin. Connect an external resistor (RCS) between this pin and ground to set peak

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

VDET

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

detect zero-crossing points for valley turn on operation.

6

FB Feedback Pin. Connect this pin to optocouplers’s collector for output regulation.
