DATA SHEET www.onsemi.com Quasi-Resonant Current-Mode Controller for High-Power Universal Off-Line Supplies NCP1380 The NCP1380 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.

NCP1380 Features
