Abstract
A Hybrid DC-DC switching converter architecture is described. The Hybrid architecture includes a capacitive converter cascaded by an inductive converter for a boost switching converter, and an inductive converter cascaded by a capacitive converter for a buck switching converter. A capacitor at an intermediate node and a switch in the capacitive converter are removed. Reducing the switching converter by one switch and one capacitor results in a smaller implementation area. A single regulation circuit and an inductor with a smaller saturation current (Isat) are used.
