Abstract
A power switching circuit receives a first power, a second power and a switching signal, and generates an output power. The power switching circuit includes a first power path and a second power path. The first power path is connected with the first power. The second power path is connected with the second power. When the switching signal in a logic high level, the first power path is in a conducting state and the second power path is in a non-conducting state. Consequently, the first power is selected as the output power by the power switching circuit. When the switching signal in a logic low level, the first power path is in the non-conducting state and the second power path is in the conducting state. Consequently, the second power is selected as the output power by the power switching circuit.
