ADAPTIVE-GAIN STEP-UP/DOWN SWITCHED-CAPACITOR DC/DC CONVERTERS

摘要

A switched-capacitor DC-DC converter has a reconfigurable power stage with variable gain ratio and/or interleaving regulation for low ripple voltage, fast load transient operation, variable output voltage and high efficiency. Since the power stage has multiple switches per capacitor, the converter exploits reconfigurable characteristics of the power stage for fast dynamic control and adaptive pulse control for tight and efficient voltage regulation.
