DESCRIPTION
Current Sense Pin. Connect an external resistor (R
CS
) between this pin and ground to set peak
current limit for the primary switch.
Ground.
Gate Drive. Gate driver for the external MOSFET transistor.
Power Supply. This pin provides bias power for the IC during startup and steady state operation.
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.
Feedback Pin. Connect this pin to optocouplers’s collector for output regulation.
