Pin Functional Description
DRAIN (D) Pin:
High-voltage power MOSFET DRAIN pin. The internal start-up
bias current is drawn from this pin through a switched high-
voltage current source. Internal current limit sense point for
drain current.
CONTROL (C) Pin:
Error amplifi er 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.
EXTERNAL CURRENT LIMIT (X) Pin (Y, M, E and L package):
Input pin for external current limit adjustment and remote
ON/OFF. A connection to SOURCE pin disables all functions
on this pin.

VOLTAGE MONITOR (V) Pin (Y & M package only):
Input for OV, UV, line feed forward with DC
overvoltage protection (OVP), remote ON/OFF and device reset.
A connection to the SOURCE pin disables all functions on this pin.
MULTI-FUNCTION (M) Pin (P & G packages only):
This pin combines the functions of the VOLTAGE MONITOR (V)
and EXTERNAL CURRENT LIMIT (X) pins of the Y package into
one pin. Input pin for OV, UV, line feed forward with DC
