Abstract
Official abstract text for this publication.
The present disclosure relates to a flexible direct current (DC)-DC converter, which includes a charge pump buck power supply and a buck power supply. The charge pump buck power supply and the buck power supply are voltage compatible with one another at respective output inductance nodes to provide flexibility. In one embodiment of the DC-DC converter, capacitances at the output inductance nodes are at least partially isolated from one another by using at least an isolating inductive element between the output inductance nodes to increase efficiency. In an alternate embodiment of the DC-DC converter, the output inductance nodes are coupled to one another, such that the charge pump buck power supply and the buck power supply share a first inductive element, thereby eliminating the isolating inductive element, which reduces size and cost but may also reduce efficiency.
First claim
Opening claim text (preview).
What is claimed is: 1. Circuitry comprising: a charge pump buck power supply comprising a charge pump buck converter having a first output inductance node, a first inductive element, an energy storage element, and a plurality of shunt pump buck switching elements coupled in series between the first output inductance node and ground, such that the first inductive element is coupled between the first output inductance node and the energy storage element; and a buck power supply…
