A digital SC converter with high efficiency and low voltage ripple

Abstract

A switched-capacitor DC-DC converter with a low output voltage ripple and high efficiency is presented in this summary. To achieve a wide input and output voltage range, a 3-clock-phase operation is proposed to achieve 6 voltage conversion ratios (VCRs) with only two discrete flying capacitors. A digital ripple reduction scheme is utilized to achieve up to… (More)
