Abstract
A power switch circuit includes a first input voltage, a first switch element, a switcher, a first bootstrap capacitor, and a second bootstrap capacitor. The first switch element includes a first control end, a first input end, and a first output end. The first input end is coupled to the first input voltage. The first output end provides an output voltage. The switcher is coupled to the first switch element. The first bootstrap capacitor is coupled to the switcher and provides a first driving voltage. The second bootstrap capacitor is coupled to the switcher and provides a second driving voltage. The first bootstrap capacitor and the second bootstrap capacitor alternately supply the first driving voltage or the second driving voltage to the first control end through an operation of the switcher.
