MM3661 is a quasi resonant control IC for AC-DC converter. This control helps to keep the EMI low by soft switching. This IC has a built-in start-up circuit that tolerates 500V voltage. It helps to improve start-up speed with the start-up circuit loss reduction. This IC contributes to the high efficiency at light-load by frequency decrease function with Burst operation. In addition, this IC is equipped with ACand load detection function or a dedicated output terminal. Thereby it is possible to realize a the start-stop control and output voltage control of the PFC circuit.
