MM3663

MITSUMI The PWM control IC for AC-DC converter MM3663 Series The PWM control IC for AC-DC converter Monolithic IC MM3663 Series Outline Features 1. Start up circuit by 500V high breakdown process reduce start up circuit loss. 2. Current mode PWM controller (select function of maximum oscillating frequency, 66kHz or 100kHz) 3. Frequency reduction function in load of middle range improve avearge efficiency. 4. Low voltage of UVLO and low supply current in oscillation stop reduce standby power more. 5. Noise diffusion, downsize filter by frequency jitter function in all range. 6. X capacitor discharge function which don't increase standby power can make the measures of EMI easy. 7. Seam of burst mode and continuous oscillation mode can be arbitrarily adjusted.Balance adjustment between standby power and output ripple. 8. Input voltage correction function of load current in over current protection realize flat correction characteristics. 9. Substantial protection functions included,...
