Abstract
This article presents a new integrated step-down
dc–dc hybrid converter that uses only nano-Henry scale inductors
at 2–5-MHz switching frequency. Since it is derived from a
Dickson-star switched capacitor (SC) converter, the proposed
converter inherits the benefit of low voltage stress on switches
while enjoying an efficient fine regulation by phase shift, similar
to a dual active bridge (DAB) converter. The converter is
optimized, designed, and fabricated in 1.7 × 1.9 mm area of
a 130-nm bipolar-C
