摘要
A DC/DC converter includes: a transformer; a main MOS transistor connected in series between a primary side inductance of the transformer and a ground potential; a synchronous rectification MOS transistor connected in series between a secondary side inductance of the transformer and the ground potential; a refluxing MOS transistor connected between a secondary side output of the transformer and the ground potential; and a controller. If an operation is stopped, the controller stops the main MOS transistor and stops the synchronous rectification MOS transistor and the refluxing MOS transistor after a lapse of a predetermined period of time.
