... The COMP pin behaves as a constant PENTAWATT HV (022Y) VIPer100B (022Y) current source, and can easily be connected to the output of an optocoupler. Note that any overvoltage due to regulation loop failure is still detected by the error amplifier through the V voltage, which cannot overpass 13V ...

... The converter enters a endless start up cycle, with a start-up duty cycle defined by the ratio of charging current towards discharging when the VIPer100B/BSP tries to start. This ratio is fixed by design 15, which gives a 12% start up duty cycle while the power dissipation at start up is approximately ...
