onsemi NCP1379
The NCP1379 hosts a high−performance circuitry aimed to powering quasi−resonant converters. 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.| Part No. | NCP1379 |
