MM3661, The quasi resonant control IC

MITSUMI The quasi resonant control IC for AC-DC converter MM3661 Series 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
