Description
This pin detects the input line voltage by sensing the bulk capacitor, and
disables the PWM when line voltage is lower than normal.
By connecting an optocoupler to this pin, the peak current setpoint is ad-
justed according to the output power demand. Internal monitoring of this
pin level triggers the fault management circuitry.
This pin senses the primary inductor current and routes it to the internal
comparator via an LEB circuit.

The driver ’s output to an external MOSFET.
This pin is connected to an external bulk capacitor of typically 10 m F.
This unconnected pin ensures adequate creepage distance between High
Voltage pin to other pins.
Connected to the high--voltage rail, this pin injects a constant current into
the V CC capacitor.
