Abstract: A voltage converter is provided. The voltage converter includes a charge pump and a switching circuit. The charge pump includes an input capacitor, where two ends of the input capacitor are electrically connected to an input end and a ground end respectively. The switching circuit includes a first switch, a second switch, a third switch, and a fourth switch, and these switches are connected in series. The first switch is electrically connected to the input end, the fourth switch is electrically connected to the ground end, a capacitor is connected in parallel with the second switch and the third switch, and an output end is electrically connected between the second switch and the third switch.
