Abstract
A DC-DC converter module includes a module substrate on which switching transistors and a controller IC chip are mounted, stud terminals mounted on a surface of the module substrate, and an inductor attached to the stud terminals such that the inductor faces the module substrate. In a plan view, the switching transistors are arranged within an area where the inductor overlaps the module substrate, whereas at least a portion of the controller IC chip is arranged outside the area.
