... PWM Current−Mode Controller for High−Power Universal Off−Line Supplies Housed in a SOIC−8 or PDIP−7 package, the NCP1216 represents an enhanced version of NCP1200 based controllers. Due to its high drive capability, NCP1216 drives large gate−charge MOSFETs, which together with internal ramp compensation and built−in frequency jittering, ease the design of modern AC− ...

... Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. NCP1216, NCP1216A Skip Cycle Comparator Internal V ...

... CC Frequency Jittering on the Internal Oscillator Sawtooth Skipping Cycle Mode The NCP1216 automatically skips switching cycles when the output power demand drops below a given level. This is accomplished by monitoring the FB pin. In normal operation, pin 2 imposes a peak current accordingly to the load value. If the load demand decreases, the internal loop asks for less peak current ...
