Power supplying circuit and power supplying method

Abstract

A power supplying circuit includes a first high-voltage switch, a first low-voltage switch, a second high-voltage switch, a second low-voltage switch, and a controller circuit. The first high-voltage switch receives a first input voltage and generates a first node voltage. The first low-voltage switch is coupled between the first high-voltage switch and an output terminal. The second high-voltage switch receives a second input voltage and generates a second node voltage. The second low-voltage switch is coupled between the second high-voltage switch and the output terminal. The controller circuit controls the first high-voltage switch, the first low-voltage switch, the second high-voltage switch, and the second low-voltage switch according to the first node voltage and the second node voltage such that an output voltage is outputted to the output terminal.
