Abstract: A DC/DC converter includes N inductors and N power modules which correspond to N phases. The N inductors each include a plurality of inductor chips that are electrically connected in parallel to each other. The plurality of inductor chips are mounted separately on a main mounting surface and a sub-mounting surface of a printed circuit board. The sub-mounting surface is opposite to the main mounting surface.
