This pin lets you adjust the level at which the cycle skipping process
takes place. Shorting this pin to ground, permanently disables the skip
cycle feature.
By connecting an Optocoupler to this pin, the peak current setpoint is
adjusted accordingly to the output power demand.
This pin senses the primary current and routes it to the internal com-
parator via an L.E.B. By inserting a resistor in series with the pin, you
control the amount of ramp compensation you need.
The driver’s output to an external MOSFET.
This pin is connected to an external bulk capacitor of typically 22 mF.
This un−connected pin ensures adequate creepage distance.
Connected to the high−voltage rail, this pin injects a constant current
into the V
