Product Details
The ON Semiconductor Quasi-Resonant Flyback Controller, High Frequency 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, to ensure light load performance with high frequency designs, the NCP1342 incorporates rapid frequency foldback with minimum peak current modulation to reduce the switching frequency quickly.
