NCP1118x mWSaver® Integrated Power Switchers onsemi NCP1118x mWSaver® Integrated Power Switchers integrate a peak current mode PWM controller, implementing mWSaver technology and a highly robust 800V SJ MOSFET. This integrated design on the NCP1118x provides a significantly enhanced performance in flyback converters. mWSaver technology decreases the controller's switching frequency and operating current at light-load conditions, which helps avoid acoustic-noise problems and even meets international power conservation standards, such as Energy Star®.
