AC/DC电源控制芯片

SCM1710B是一款高度集成的电流模式PWM控制器，适用于离线式AC-DC开关电源。在SCM1710B内部，芯片工作频率是经过修调的，具有很高的精度，并且可通过外接不同阻值的电阻改变其最大工作频率；轻载时，芯片的工作频率和峰值电流幅度会随着负载的减小而降低，接近空载时工作在间歇模式，从而可使变换器在整个负载范围都维持高效率，也减小了待机功耗；芯片集成了各种补偿电路，无需片外增加器件就能实现极高的输出电压精度、优良的动态响应和极低的输出电压温度系数；自带软启动功能，改善启机应力并有效抑制轻载输出过冲；采用软驱动和抖频技术改善EMI问题；内置了管理时钟，防止干扰使环路进入死区。此外，SCM171
