Abstract
A power converter and method using a flying capacitor, a first transistor, a second transistor, a third transistor, a fourth transistor, and a driver circuit are presented. The first transistor is coupled between an input terminal and a first terminal of the flying capacitor. The second transistor is coupled between the first terminal of the flying capacitor and an output terminal. The third transistor is coupled between the output terminal and a second terminal of the flying capacitor. The fourth transistor is coupled between the second terminal of the flying capacitor and a reference potential. The driver circuit is coupled between a high side power rail and a low side power rail. There is a regulation circuit to regulate a high side voltage of the high side power rail such that the regulated high side voltage is independent of an input voltage at the input terminal.
