Abstract:
A DC-DC converter includes a protection function for handling a reverse connection state, and a protection function for handling a predetermined abnormality other than a reverse connection state, while reducing conduction loss. The DC-DC converter includes a first protection circuit unit, and a switching element on a first conductive path of a high-voltage side switches to an OFF state upon a predetermined abnormal state being detected to prevent a current from flowing into a voltage conversion unit. Furthermore, a reverse connection protection circuit unit and a switching element, on a third conductive path between the voltage conversion unit and a reference conductive path, is configured to switch to an off state if at least a low-voltage side power supply unit is in a reverse connection state, preventing a current from the reference conductive path. Thus, a current is prevented from flowing toward a power supply that is improperly connected.

Claim (Index 11):
The DC-DC converter according to  claim 9 , further comprising:\n an operation control unit that sequentially operates the plurality of voltage conversion units, wherein if the abnormal state detection unit detects the abnormal state while one of the plurality of voltage conversion units is operating, and the abnormal state detection unit does not detect the abnormal state while another one of the plurality of voltage conversion units is operating, the first protection circuit unit selectively switches the second switching element on the individual input path that is an input path to the one of the plurality of voltage conversion units from which the abnormal state is detected, into an OFF state, and maintains the second switching element on the individual input path that is an input path to the other voltage conversion unit from which an abnormal state is not detected, in an ON state.
