Abstract
This article presents a 12-to-1 V quad-output
switched-capacitor buck (SCB) converter with shared dc capac-
itors ( CDCs). First, we proposed single-output SCB achieving a
high efficiency, with small switch area and small inductor volume
under several-ampere conditions. Each single-output SCB has
two CDCs. Second, based on the single-output SCB, we proposed
multiple-output SCB converter that shares the two CDCs among
the channels. The CDC-sharing improves the power density and
efficiency under u
