Abstract
This article presents a 12-to-1 flying capacitor cross-
connected (CCC) converter with an inserted duty cycle ( D) > 0.5
control for fast transient response. As analyzed, CCC and double-
step-down (DSD) converters have almost the same power loss
and silicon area, while the CCC uses a much smaller input
capacitance. Besides, with the proposed D > 0.5 control, the
CCC achieves > 2× inductor current slew rate and thus a faster
transient response, when compared with a conventional DSD con-
verter. S
