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.
Ground.
Base Drive. Base driver for the external NPN transistor.
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 (R
CS
) 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) / R
CS
. For more
detailed information, see Application Information.
