According to one embodiment, a power supply circuit includes a switching control unit that compares a DA converted value of the high order bit of a digital compensation value calculated from an output voltage of a smoothing circuit with a detection value of a current flowing into the smoothing circuit and controls the switching of a switching element on the basis of a signal obtained by shifting the timing of the comparison result on the basis of the low order bit of the digital compensation value.
