Description :
Mitsubishi IC type M51977P, M51977FP are the off-line primary PWM controller which are especially designed for SMPS to get the regulated DC voltage from AC power supply. As the totempole type high power-driver-circuit is integrated in these IC. these IC can drive the MOSFET with fast rise and fast fall ouput pulse.
