Pin Description
Pull the pin up or down to latch ? off the controller. An internal current source allows
the direct connection of an NTC for over temperature detection
A pull ? down optocoupler controls the output regulation.
Senses the primary current for current ? mode operation, and provides a mean for
overpower compensation adjustment.
IC ground
Drives an external MOSFET
This supply pin accepts up to 28 Vdc
Connects to the bulk capacitor or the rectified AC line to perform the functions of
start ? up current source and brown ? out / line overvoltage detections
