A DC/DC converter (1), wherein a switching element (n_dr) of a conversion circuit (10) enters the off state by the inactivation of an on signal (Son), and enters the on state by the inactivation of an off signal (Soff). A control circuit (20) includes an on signal generation unit (40A) for generating the on signal (Son), and an off signal generation unit (40B) for generating the off signal (Soff). The on signal generation unit (40A) places the on signal (Son) in an active state for the period from the time the off signal (Soff) is inactivated until a time elapses that is determined according to the size of an input direct-current voltage (Vin). The on signal generation unit (40B) places the off signal (Soff) in an active state for the period from the time the on signal (Son) is inactivated until a time elapses that is determined according to the size of the input direct-current voltage (Vin). |
