Abstract

Embodiments for at least one method and apparatus of generating a regulated voltage are disclosed. One method includes generating the regulated voltage through controlled closing and opening of a series switch element and shunt switch element. This method includes closing the series switch element during a first period, the series switch element comprising a plurality of series switch elements segments. The method includes applying a switching gate voltage to gates of series switching transistors of a subset of the plurality of series switch elements segments of the series switch element, wherein only the series switching transistors of the subset of the plurality of series switch elements segments of the series switch element turn on, while series protection transistor of more than the subset of the plurality of series switch elements segments of the series switch element turn on. The shunt switch element during is closed during a second period.
