NAME

DESCRIPTION

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.

2,4,7

Ground.

Base Drive. Base driver for the external NPN transistor.

VDD

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

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

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.

Exposed Pad shown as dashed box. The exposed thermal pad should be connected to board

ground plane and pin 4. The ground plane should include a large exposed copper pad under the

package for thermal dissipation (see package outline). The leads and exposed pad should be

flush with the board, without offset from the board surface.
