com powering quasi−resonant converters.
Capitalizing on a novel QUASI−RESONANT PWM valley−lockout system, the controller shifts gears and reduces the CONTROLLER FOR HIGH POWER switching frequency as the power loading becomes lighter.
This AC−DC WALL ADAPTERS 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.
The controller takes benefit ...
