Typical Application for NCP1379 Quasi-Resonant Current-Mode Controller for High-Power Universal Off-line Supplies

Typical Application for 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
