Abstract
An electronic device includes a power receiving unit that receives power from an external device, a first voltage conversion unit that generates a first output voltage regardless of a variation of the input voltage, a second voltage conversion unit in which a second output voltage varies due to a variation of the input voltage, a voltage supply unit that steps up or down the first output voltage or the second output voltage and supplies the output voltage to a load circuit of the electronic device, and a control unit that performs control so as to supply power to the load circuit of the electronic device by switching to the first voltage conversion unit or the second voltage conversion unit based on a voltage supplied to the load circuit of the electronic device.
