摘 要: 本文介绍了采用Soft-Skip开关模式以降低电源待机功耗的原理。这种待机状态下的开关模式可以有效降低因开关频率过低产生的音频噪声,并且可以对进入Soft-Skip模式的电平进行调整以适应不同的负载需求。最后,试制了一台输出为12V/5A的反激电源对这种待机模式进行验证。 Principle of using Soft-Skip switching mode to reduce standby power consumption of power supply was introduced. This switch mode of standby can reduce acoustic noise aroused by lower switch frequency effectively, And the entrance level of Soft-Skip mode can be adjusted to adapt various applications. At last, a 12V/5A Flyback power supply was made to test and verify.
