CYStech Electronics Corp. Spec. No. : C595N6 Issued Date : 2012.02.23 Revised Date : Page No. : 1/12 Current Mode PWM Controller MC3265N6 Description MC3265 is a highly integrated current mode PWM control IC optimized for high performance low standby power offline flyback converter applications. To improve the efficiency, MC3265 works at QR (Quasi-Resonant) mode or fixed frequency(52KHz) while the loading is high and the line voltage is high or low. At normal loading, MC3265 works at QR mode and the frequency is limited to 95KHz. 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.
