Zusammenfassung:	An apparatus is disclosed for implementing a multi-mode direct-current (DC)-to-DC power converter. In an example aspect, the apparatus includes a DC-to-DC power converter with a flying capacitor, an inductor, and four switches. The inductor is coupled between a second node and a battery node. A first switch is coupled between a first node and a first terminal of the flying capacitor. A second switch is coupled between the first terminal and the second node. A third switch is coupled between a second terminal of the flying capacitor and the second node. A fourth switch is coupled between the second terminal and a ground node. The DC-to-DC power converter is configured to selectively transfer power from the first node to the battery node according to a first operational mode and transfer other power from the battery node to the first node according to a second operational mode.
