Core reset detection and OVP
The auxiliary FLYBACK signal ensures discontinuous operation and
offers a fixed overvoltage detection level of 7.2 V.

Description
2
FB
Sets the peak current setpoint
By connecting an Optocoupler to this pin, the peak current setpoint is
adjusted accordingly to the output power demand. By bringing this pin
below the internal skip level, device shuts off.
3
CS
Current sense input and skip
cycle level selection
This pin senses the primary current and routes it to the internal
comparator via an L.E.B. By inserting a resistor in series with the pin, you
control the level at which the skip operation takes place.

Supplies the IC
This pin is connected to an external bulk capacitor of typically 10 F.
8
HV
High-voltage pin
Connected to the high-voltage rail, this pin injects a constant current into
the V
CC
bulk capacitor.
