The quasi resonant control IC for AC-DC converter
Monolithic IC MM3661 Series
Outline
This IC 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 500V tolerates voltage. It helps to which 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 AC detection function and 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.
