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 4):
The DC-DC converter according to  claim 1 ,\n wherein the secondary-side power supply unit is configured as the low-voltage side power supply unit, the primary-side power supply unit is configured as the high-voltage side power supply unit, and the voltage conversion unit is configured to step down a DC voltage applied to the first conductive path and output the resulting voltage to the second conductive path, the abnormal state detection unit detects, as the abnormal state, a predetermined overvoltage state of at least the second conductive path, and the first protection circuit unit switches the second switching element to an OFF state upon the abnormal state detection unit detecting an overvoltage state of the second conductive path.
