NCP1336ADR2G Datasheet PDF - ON Semiconductor

●Quasi-Resonant Current Mode Controller for High Power Universal Off-Line Supplies

●The NCP1336 hosts a high−performance circuitry aimed to powering quasi−resonant converters. Capitalizing on a novel

●valley−lockout system, the controller shifts gears and reduces the switching frequency as the power loading becomes lighter. This results in a stable operation despite switching events always occurring in the drain−source valley. This system works down to the 4th valley and toggles to a variable frequency mode beyond, ensuring an excellent standby power performance.
