Description
MC7773N6 is a highly integrated current mode PWM control IC optimized for high performance low
standby power offline flyback converter applications.
To meet the international power conservation requirements, optimized green mode is integrated to improve
the efficiency at light or no load conditions with no audible noise.
Slope compensation is integrated to ensure the stability at high load. Lead edge blanking is integrated to
prevent the false trigger at the transition of the switch. Soft switching control at the gate drive can improve
the EMI performance of the power supply. The Gate-drive output is clamped at 12V to protect the power
MOS.
