Abstract
A power switch circuit is provided. The power switch circuit includes a power switch, a sensing circuit, a selecting circuit and a modulating circuit. The power switch has an output terminal for providing an output voltage and an output current. The sensing circuit is coupled to the power switch, senses the output current and outputs a current sensing signal. The selecting circuit is respectively coupled to the output terminal and the sensing circuit. The selecting circuit controls the sensing circuit according to the output voltage, so that the sensing circuit selectively outputs a first sensing current or a second sensing current as the current sensing signal. The modulating circuit is coupled to the sensing circuit and a control terminal of the power switch. The modulating circuit outputs a controlling voltage to the control terminal of the power switch, and modulates the controlling voltage according to the current sensing signal.
