PIN DESCRIPTIONS

PIN NAME

DESCRIPTION

1

SW

Switch Drive. Switch node for the external NPN transistor. Connect this pin to the external power

NPN’s emitter. This pin also supplies current to VDD during startup.

2

G Ground.

3

BD Base Drive. Base driver for the external NPN 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.

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

6

CS current limit for the primary switch. The peak current limit is set by (0.396V × 0.9) / RCS. For more

detailed information, see Application Information.
