Pin Functional Description
DRAIN Pin:
Output MOSFET drain connection. Provides internal bias
current during start-up operation via an internal switched
high-voltage current source. Internal current sense point.
CONTROL Pin:
Error amplifier and feedback current input pin for duty cycle
control. Internal shunt regulator connection to provide inter-
nal bias current during normal operation. It is also used as
the connection point for the supply bypass and auto-restart/
compensation capacitor.
SOURCE Pin:
YN package – Output MOSFET source connection for high
voltage power return. Primary side circuit
common and reference point.
PN and GN package – Primary-side control circuit common
and reference point.
SOURCE (HV RTN) Pin: (P and G package only)
Output MOSFET source connection for high voltage power
return.
