MC3265N6 Overview
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.
