A direct current (DC)/DC converter is provided. The DC/DC converter includes multiple switches, a capacitor, an inductor, and at least one processor, wherein, when the output voltage of the DC/DC converter is less than a first threshold voltage, the at least one processor is configured to control an on/off state of the multiple switches so as to increase the current output from the inductor based on the current, which is output from the inductor, being less than a first threshold current, and control a second switch and a fourth switch to be in an on state or control a first switch and a third switch be in the on state to allow one end or the other end of the capacitor to be connected to one end of the inductor, based on the current, which is output from the inductor, being increased to be greater than or equal to the first threshold current.
