Abstract
A DC-DC converter includes a high-side switch coupled between a first power supply and an output terminal, a low-side switch coupled between a second power supply and the output terminal, an inductor coupled to the output terminal, and a reverse current monitoring circuit that determines that a reverse current from the inductor to the output terminal occurs when the output terminal becomes a high voltage during a state in which the high-side switch and the low-side switch are in a dead time.
