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, and generating an output voltage by filtering the switching voltage with an output inductor and a load capacitor. The method further includes generating an assisting current based on a value of current conducted through the output inductor, and assisting the load current by summing the assisting current with the current conducted through the inductor.
