A switching voltage regulator for a power converter is disclosed. The power converter includes a power source selector, a regulator controller, and an inductor. The switching voltage regulator includes: a first power input terminal; a second power input terminal; a first switch having a first terminal coupled with the first power input terminal; a second switch having a first terminal coupled with the second power input terminal; a third switch having a first terminal coupled with a second terminal of the first switch and a second terminal of the second switch; and a fourth switch having a first terminal, coupled with a second terminal of the third switch, for coupling with the inductor. Control terminals of the first switch and the second switch are utilized for coupling with the power source selector. Control terminals of the third switch and the fourth switch are utilized for coupling with the regulator controller.
