Function
Adjust the skipping peak current
Pin Description
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.
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. Skip cycle occurs when
FB falls below Vpin1.

Current sense input
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 22 m F.
This unconnected pin ensures adequate creepage distance.
Connected to the high ? voltage rail, this pin injects a constant current into
the V CC capacitor during the startup sequence.
