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 the 4th valley and toggles to a variable frequency mode beyond, ensuring an excellent standby power performance.
Features
• Quasi−Resonant Peak Current−Mode Control Operation
