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.
2,4,7
GND
Ground.
8
BD
Base Drive. Base driver for the external NPN transistor.
6
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.
3
CS
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.
EP
EP
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.
