Abstract

In an example, a dual-phase inverting buck-boost power converter for use with at least first and second energy storage elements includes an inverting buck-boost power converter and an inverting boost converter. In an example, the inverting buck-boost power converter is coupled between an input node and an output node of the dual-phase inverting buck-boost power converter and includes a first plurality of switches operable to couple to the first energy storage element, wherein the inverting buck-boost power converter is operable to supply a first load current. In an example, the inverting boost converter is coupled in parallel with the inverting buck-boost power converter between the input node and the output node of the dual-phase inverting buck-boost power converter and includes a second plurality of switches operable to couple to the first and the second energy storage elements, wherein the inverting boost converter is operable to supply a second load current.
