MM3661

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 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. Features 1. Absolute maximum rating (HV pin) 2. Recommended operating condition (VDD pin) 3. PFC drive voltage (PSTB pin) 4. Operating current 5. Frequency 6. The range of temperature 7. Light load burst operation 8. Frequency decr...
