CYStech Electronics Corp. Spec. No. : C151N6 Issued Date : 2012.11.08 Revised Date : Page No. : 1/11 Current Mode PWM Controller MC7773N6 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.
