AC/DC电源控制芯片

SCM1733ASA是应用于中小功率AC/DC反激式开关电源的高性能电流模式PWM控制器，内置高压功率 MOS，最大输出功率达20W，待机功耗低于75mW。SCM1733ASA 具有极低的启动电流和工作电流，可实现低的损耗并保证可靠启动。SCM1733ASA满载工作时，PWM开关频率固定；降低负载后，进入绿色模式，开关频率降低；在空载和轻载时，进入间歇模式，以降低开关损耗。其先进的多种控制模式可以降低开关损耗并提高变换器转换效率。SCM1733ASA提供软启动控制以降低MOS应力、频率抖动控制以获得良好的 EMI、间歇模式频率高于22KHz无音频噪声，及多种自恢复保护，如VDD欠压锁（UVLO
