Abstract
An exemplary electronic device includes a controller, a first convertor, a second convertor, and a switching unit. The first convertor is configured for receiving a first voltage from an external power supply and converting the first voltage into a second voltage. The controller is coupled to the first convertor for generating a start signal when receiving the second voltage. The second convertor is connected to the controller for receiving the first voltage, converting the first voltage into a third voltage to power an operating unit of the electronic device, and converting the first voltage into a fourth voltage to power the controller when receiving the start signal. The switching unit is coupled to the controller and the first convertor for disabling the first convertor when the controller receives the fourth voltage. A related power supply unit is also provided.
