    Abstract: An electronic device is provided. When the electronic device is at a power exhaustion state and a first external device with a charging function is coupled to a connection interface to provide a first supply voltage to a power pin of the connection interface, a voltage regulation unit transforms the first supply voltage to a first operation voltage, and a storage unit powered by the first operation voltage outputs device information of the electronic device to the first external device through a signal transmitting/receiving pin set of the connection interface. When the first external device provides a second supply voltage to the power pin in response to the device information, the electronic device enters a charging mode. In the charging mode, the charging unit provides a charging voltage according to the second supply voltage to charge the battery unit and provides a second operation voltage to a processing unit.

    Abstract: A method for reducing audible noise of a power supply provides a PWM signal for controlling a power converter. First, a feedback voltage is produced by detecting an output voltage of the power converter. Afterward, a burst-in voltage and a burst-out voltage are set. Afterward, a voltage level of the burst-in voltage or a voltage level of the burst-out voltage is dynamically varied. Afterward, the PWM signal is switched off when the feedback voltage is less than the burst-in voltage. Final, the PWM signal is switched on when the feedback voltage is greater than the burst-out voltage.
