Overview

High-Voltage, Quasi-Resonant, Controller Featuring Valley Lock-Out Switching NCP1341 The NCP1341 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 NCP1341 can enable no−load power consumption below 30 mW.
The NCP1341 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 NCP1341 enters quiet−skip mode to manage the power delivery while minimizing acoustic noise.
The NCP1341 integrates ...
