A DC/DC converter 200A is provided with N-numbered inductors L1_1 to L1_N and N-numbered power modules 220_1 to 220_N which correspond to N-numbered phases. At least one of the N-numbered power modules is mounted on a sub-mounting surface SB opposite to a main mounting surface SA of a printed circuit board 300A. Un convertisseur courant continu/courant continu (200A) est pourvu de N bobines d'induction L1_1 à L1_N et de N modules de puissance 220_1 à 220_N qui correspondent à N phases. Au moins un des N modules de puissance est monté sur une surface de montage auxilaire SB opposée à une surface de montage principale SA d'une carte de circuit imprimé 300A. ＤＣ／ＤＣコンバータ２００Ａは、Ｎフェーズに対応付けられるＮ個のインダクタＬ１＿１～Ｌ１＿Ｎと、Ｎ個のパワーモジュール２２０＿１～２２０＿Ｎを備える。Ｎ個のパワーモジュールの少なくともひとつは、プリント基板３００Ａの主実装面ＳＡと反対側の副実装面ＳＢに実装される。
