ORDERING INFORMATION
PIN
NAME
DESCRIPTION
1
CS
Current Sense Pin. Connect an external resistor (RCS) between this pin and ground to set peak
current limit for the primary switch.
2
GND
Ground.
3
GATE
Gate Drive. Gate driver for the external MOSFET transistor.
4
VDD
Power Supply. This pin provides bias power for the IC during startup and steady state operation.
5
VDET
Valley Detector Pin. Connect this pin to a resistor divider network from the auxiliary winding to
detect zero-crossing points for valley turn on operation.
6
FB
Feedback Pin. Connect this pin to optocouplers’s collector for output regulation.
