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
NCP1379 Features
* a pin to implement a combined brown
* out/overvoltage protection. Particularly well suited for TVs power supply applications, the controller features a low startup voltage allowing the use of an auxiliary power supply to power the device. Features
* Quasi
* Resonant Peak Current
