Product Details
The ON Semiconductor series NCP1343 is a highly integrated quasi−resonant fly back controller suitable for designing high−performance off−line power converters. The NCP1343 features a proprietary valley−lockout circuitry, ensuring stable valley switching. This system works down to the 6th valley and transitions to frequency fold back mode to reduce switching losses. As the load decreases further, the NCP1343 enters quiet−skip mode to manage the power delivery while minimizing acoustic noise.
