Pin Functional Description  
SOURCE (S) Pin:  
DRAIN (D) Pin:  
Output MOSFET source connection for the power return.  
Primary side control circuit common and reference point.  
High-voltage power MOSFET drain output. The internal startup  
bias current is drawn from this pin through a switched high-  
voltage current source. Internal current limit sense point for  
drain current.  
Tab internally connected  
to SOURCE pin  
CONTROL (C) Pin:  
Error amplifier and feedback current input pin for duty cycle  
control. Internal shunt regulator connection to provide internal  
bias current during normal operation. It is also used as the  
connection point for the supply bypass and auto-restart/  
compensation capacitor.  
(See layout considerations)

P Package (DIP-8)  
G Package (SMD-8)  
LINE-SENSE (L) Pin:  
Input pin for overvoltage (OV), undervoltage (UV) lock out, line  
feed-forward with the maximum duty cycle (DCMAX) reduction,  
remote ON/OFF and synchronization. A connection to  
SOURCE pin disables all functions on this pin.
