Hi6603 外驱负边SOT23-6电源芯片
Hi6603 is 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. Hi6603 offers many protection functions with auto self-recovery feature, including Cycle-by-Cycle current limiting, over load protection (OLP) and under voltage lockout (UVLO). Excellent EMI performance is achieved with frequency jitter technique together with soft switching control at the totem pole gate driver. Hi6603 is offered in SOT23-6 packages.
