Abstract
A DC/DC converter includes: multiple channels each including a switching circuit and an inductor; an output line having one end connected to the other end of the inductors of the multiple channels and the other end connected to a load; and a controller. The multiple channels include first to third channels, and the inductors of the first and second channels have a larger inductance value than the inductor of the third channel. When current flowing in the load is first current, the controller controls the switching circuits so that only the first channel is activated; and when the current flowing in the load is second current that is larger than the first current, the controller controls the switching circuits so that the first and second channels are operated in-phase and the third channel is operated in a phase different from the phase of the first and second channels.
