Abstract: The voltage regulator includes a series switch element, and a shunt switch element, wherein a switching voltage is generated through controlled closing and opening of the series switch element and the shunt switch element. The voltage regulator further includes a switched output filter for filtering the switching voltage and generating an output voltage, wherein the switched output filter comprises a plurality of capacitors that are selectively connected and included within the switched output filter. The voltage regulator further includes a mode controller, wherein the mode controller is operative to disconnect at least one of the plurality of capacitors upon receiving a first indicator, where disconnecting causes the at least one of the plurality of capacitors to electrically float, wherein while the at least one capacitor is disconnected the output voltage is changed from a first value to a second value, return the output voltage to at least one value.

Abstract: Embodiments for at methods, apparatus and systems for operating a voltage regulator are disclosed. One method includes generating, by a switching controller, a switching voltage through controlled closing and opening of a series switch element and a shunt switch element. Further, the method includes generating, by a switchable output filter, a regulated output voltage by filtering the switching voltage, wherein the switchable output filter comprises a plurality of capacitors that are selectively included within the switchable output filter. One apparatus includes a switching voltage regulator, wherein the switching voltage regulator includes a series switch element, a shunt switch element, a switching controller and a switched output filter. The switching controller is configured to generate a switching voltage through controlled closing and opening of the series switch element and the shunt switch element. The switched output filter filters the switching voltage and generates a regulated output voltage, wherein the switched output filter includes a plurality of capacitors that are selectively included within the switched output filter.
