Abstract: A power supply circuit and method for driving an electronic device that operates in a first mode or a second mode is provided. The power supply circuit includes a pulse width modulation (PWM) controller configured to convert an input voltage to an output voltage, and a driving circuit that includes a switching element whose switching state is controlled in accordance with a mode change signal corresponding to the first and second modes. The driving circuit is configured to drive the PWM controller by switching off the switching element and supplying a first voltage to the PWM controller, in response to the mode change signal indicating that the electronic device operates in the first mode. When it is indicated that the electronic device operates in the second mode, the driving circuit switches on the switching element and supplies a second voltage to the PWM controller through the switching element.
