摘要： In a normal mode, the power supply is fed back in a close loop, but in a power saving mode, the power supply is fed back in an open loop. When it is detected that the power supply is continuously fed back in the open loop and in a substantially zero output status, the power supply circuit enters a power down status. If the back-stage circuit needs power supply again, then the feedback is switched to the close loop and the power supply circuit enters the normal mode.
