Abstract
This article presents a single-mode dual-path buck-
boost converter (SDBBC) for mobile devices powered by lithium-
ion batteries. Unlike the conventional buck-boost converter
(CBBC), this SDBBC conducts buck and boost operations using
a hybrid structure with two flying capacitors ( C
F1, CF2)a n do n e
inductor. This hybrid structure eliminates any mode transition
between circuit configurations, covering both the buck and boost
operations continuously within a single-mode operation. By con-
