NCP1379 Quasi-Resonant Current-Mode Controller for High-Power Universal Off-line Supplies The NCP1379 hosts a high performance circuitry aimed to powering quasi resonant converters. Capitalizing on a proprietary 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.
