Charge pump with Active Cycle regulation-closing the gap between linearand skip modes

摘要

Active Cycle regulation, a novel dual-loop regulation technique for charge pumps closes the gap between conventional "linear" and "skip" modes. It produces about the ripple of a "linear" controlled charge pump which is one order of magnitude less than the ripple of a "skip" mode converter. At the same time, it consumes just the quiescent current of a "skip" controlled charge pump, which is a few orders of magnitude less than that of a "linear" one. Thus it combines the best of the two worlds the authors have seen so far.
