Title

New Switched-Capacitor Dc-Dc Converter With Improved Line And Load Regulations

Abstract

A new switched-capacitor (SC) step-down dc-dc converter is presented. It exhibits smaller size, lighter weight and stronger regulation capabilities than previous SC converters of the same power ratings. Its operation principles and analysis are described in detail and an accurate as well as an approximate expression governing input, output and circuit parameters is presented. A discussion on the achievable conversion efficiency is also given. A 12 V/5 V prototype based on the proposed topology has been implemented and tested. Theoretical prediction of its regulation and efficiency is verified experimentally.
