**The NCP1246 is a new fixed−frequency current−mode controller featuring
the Dynamic Self−Supply. This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal startup current source to supply the controller during start−up, transients, latch, stand−by etc. This device contains a special HV detector which detect the application unplug from the AC input line and triggers the X2 discharge current. This HV structure allows the brown−out detection as well.**
It features a timer−based fault detection that ensures the detection of
overload and an adjustable compensation to help keep the maximum power
independent of the input voltage.
Due to frequency foldback, the controller exhibits excellent efficiency in
light load condition while still achieving very low standby power consumption.
Internal frequency jittering, ramp compensation, and a versatile latch input
make this controller an excellent candidate for the robust power supply
designs.
A dedicated Off mode allows to reach the extremely low no load input power
consumption via “sleeping” whole device and thus minimize the power
consumption of the control circuitry.
