A 3.3 V 0.1–1 A hybrid buck-boost converter with 85–97% power efficiency range highly-suited for battery-powered devices using low-profile high-DCR inductor
Conventional four-switch buck-boost converter (FBBC) has been widely used for battery-
powered portable devices when a voltage between the min and max voltages of the battery
is needed. However, its power efficiency is limited because of high conduction and switching
losses. In this paper, a power-efficient hybrid buck-boost converter (HBUBOC) is presented.
The proposed HBUBOC reduces R ON and DRC conduction loss, and switching loss
simultaneously, thus, achieving high efficiency in both the buck and boost modes, over a …
