T E C H N O L O G Y AT3263 Current Mode PWM Controller
AT3263 is highly integrated current mode PWM control IC optimized for high performance low standby power offline fly back 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 18V to protect the power MOS. AT3263 offers many protection functions with auto self-recovery feature, including Cycle-by-Cycle Features ●Frequency jitter function to improve EMI performance of power supply ●No-audible-noise green mode Control ● External Programmable PWM Switching Frequency ● Int [ … ]
