Description
This pin lets you adjust the level at which the cycle skipping process takes
place.
By connecting an Optocoupler to this pin, the peak current setpoint is adjus-
ted accordingly to the output power demand.
This pin senses the primary current and routes it to the internal comparator
via an L.E.B.
The driver ’s output to an external MOSFET.
This pin is connected to an external bulk capacitor of typically 10 m F.
This un ? connected pin ensures adequate creepage distance.
Connected to the high ? voltage rail, this pin injects a constant current into
the V CC bulk capacitor.
