com Quasi-Resonant Flyback Controller, High Frequency NCP1342 The NCP1342 is a highly integrated quasi−resonant flyback controller suitable for designing high−performance off−line power converters.
With an integrated active X2 capacitor discharge feature, the NCP1342 can enable no−load power consumption below 30 mW.
The NCP1342 features a proprietary valley−lockout circuitry, ensuring stable valley switching.
This system works down to the 6th valley and transitions to frequency foldback mode to reduce switching losses.
As the load decreases further, the NCP1342 enters quiet−skip mode to manage the power delivery while minimizing acoustic noise.
To ensure light load per...
