Real-time standby voltage adjustment circuit

摘要

A real-time standby voltage adjustment circuit includes a switch control circuit controlled by a power saving control signal provided by a personal computer for generating a switch signal. A switch device is controlled by the switch signal for receiving a working voltage provided by a power supply of the personal computer and selectively outputting the same. A converting control circuit receives an adjust voltage signal generated by an adjustment and switch circuit. The converting control circuit is controlled by the power saving control signal for applying the adjust voltage signal back to the adjustment and switch circuit thereby controlling the adjustment and switch circuit to adjust a standby voltage provided by the power supply and output an adjusted standby voltage.
