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.
