Switched-Capacitor DC-DC Converters
6.1 Introduction
The development of switched-capacitor (SC) direct-current-to-direct-current (DC-DC)
converters is motivated by the ever-increasing demands for a small-form-factor (i.e.,
small-size and light-weight), high-conversion-effi ciency, and low-cost power manage-
ment system, which is the best candidate suitable to meet the needs of continuously
shrinking portable electronic devices such as MP3 players, cellular phones, PDAs,
and so on.
Modern portable electronic devices must be powered by batteries (standard LiIon,
Ni/H, solar-cell, fuel-cell, and so on). When being used for the fi rst time, a batter ...
