Abstract
A method for powering one or more loads from a varying input voltage comprises controlling a primary switch to selectively apply the input voltage to energize an inductor, controlling a load switch to selectively connect the inductor to the load, monitoring one or more load parameters to determine load conditions, and, when the load conditions meet a load requirement, disconnecting the load from the inductor and directing any remaining current in the inductor to a energy storage element.
