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 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.
EXTERNAL CURRENT LIMIT (X) Pin:
Input pin for external current limit adjustment remote ON/OFF
and device reset. A connection to SOURCE pin disables all
functions on this pin. This pin should not be left floating.
VOLTAGE MONITOR (V) Pin:
Input for OV, UV, line feed forward with DCMAX reduction, output
overvoltage protection (OVP), remote ON/OFF. A connection to
the SOURCE pin disables all functions on this pin. This pin should
not be left floating.
FREQUENCY (F) Pin:
Input pin for selecting switching frequency 132 kHz if connected
to SOURCE pin and 66 kHz if connected to CONTROL pin. This
pin should not be left floating.
SOURCE (S) Pin:
Output MOSFET source connection for high-voltage power return.
Primary-side control circuit common and reference point.
