Abstract
Power converters, charge pumps and methods which are capable of regulating output voltage are presented. A power converter has a capacitive element, a first transistor, a second transistor, a third transistor, and a fourth transistor. The first transistor is coupled between an input terminal and a first terminal of the capacitve element. The second transistor is coupled between the first terminal of the capacitve element and an output terminal. The third transistor is coupled between the output terminal and a second terminal of the capacitive element. The fourth transistor is coupled between the second terminal of the capacitive element and a reference potential. The power converter has a control circuit to control, during a first time interval of a voltage regulation mode, one of the four transistors such that the one of the four transistors is operated as a controllable power source for regulating an output voltage.
