Advanced Multiphasing Switched-Capacitor DC-DC Converters: Pushing the Limits of Fully Integrated Power Management

By Nicolas Butzen and Michiel Steyaert

Book Overview

This book gives a detailed analysis of switched-capacitor DC-DC converters that are entirely integrated on a single chip and establishes that these converters are mainly limited by the large parasitic coupling, the low capacitor energy density, and the fact that switched-capacitor converter topologies only have a fixed voltage conversion ratio. The authors introduce the concept of Advanced Multiphasing as a way to circumvent these limitations by having multiple out-of-phase parallel converter cores interact with each other to minimize capacitor charging losses, leading to several techniques that demonstrate record efficiency and power-density, and even a fundamentally new type of switched-capacitor topology that has a continuously-scalable conversion ratio.

Provides single-source reference to the recently-developed Advanced Multiphasing concept;Enables greatly improved performance and capabilities in fully integrated switched-capacitor converters;Enables readers to design DC-DC converters, where multiple converter cores are put in parallel and actively interact with each other over several phases to improve their capabilities.
