Abstract:
The present invention realizes a DC-DC converter that is provided with a reverse flow protection function, while reducing conduction loss. A DC-DC converter includes: a voltage conversion unit that steps down a voltage applied to a first conductive path and output the resulting voltage to a second conductive path; a reverse flow state detection unit that detects a reverse flow state of a current flowing through the second conductive path; and a reverse protection control unit that performs a protecting operation when a current flows in a reverse direction. A switching element is provided on a third conductive path that is located between a voltage conversion unit and a reference conductive path, and the reverse protection control unit operates to switch the switching element to an OFF state upon a reverse flow state being detected.

Claim (Index 4):
The DC-DC converter according to  claim 1 ,\n wherein the second conductive path is a path that is electrically connected to the power supply unit, and the DC-DC converter further comprises a reverse connection protection circuit unit that includes a fourth switching element that is provided on the third conductive path and switches to an OFF state in which the fourth switching element blocks conduction through the third conductive path and an ON state in which the fourth switching element releases the blocking, the fourth switching element switching to an ON state when the power supply unit is in a regular connection state, and switching to an OFF state when the power supply unit is in a reverse connection state.
