Abstract
According to one embodiment, a power supply circuit includes a smoothing capacitor that is charged with a charge current from an output transistor and outputs a voltage as an output voltage; a control loop that controls a conduction state of the output transistor depending on a difference value between the output voltage and a reference voltage; and a gain adjustment circuit that adjusts a gain of the control loop depending on magnitude of the charge current after the charge starts.
