Abstract:
Provided is a multiphase DC-DC converter having a plurality of voltage conversion units, and detect an abnormality in any phase and to remain activated with a phase other than the faulty phase while the faulty phase is reliably protected. A DC-DC converter includes a plurality of voltage conversion units that are in parallel between an input-side conductive path and an output-side conductive path. Each of the voltage conversion units includes on an individual input path, a protective switch element, and a protective switch element disposed on an individual output path. The DC-DC converter further includes a protective abnormality identifying unit configured to identify a range in which a protective switch element is abnormal, and an operation control unit configured to cause, if the range in which a protective switch element is abnormal has been identified, any remaining conversion unit other than the range to perform a voltage conversion operation.

Claim (Index 4):
The DC-DC converter according to  claim 2 ,\n wherein the protective abnormality identifying unit is configured to identify, at least when an ignition switch is switched from OFF to ON, a conversion unit in which a protective switch element is abnormal, or a group including a conversion unit in which a protective switch element is abnormal with a subset or all of the plurality of voltage conversion units constituting the multiphase conversion unit serving as a detection target.
