Abstract
Various embodiments of the invention provide extend the switching frequency range of DC/DC multiphase switching regulators in order to overcome prior art frequency limitations in the number of available phases, for example, in low input to output ratio applications. In certain embodiments, this is accomplished by enabling partial overlap between multiple phases using asynchronous logic. The invention is easily scalable without introducing significant silicon area penalties.
