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.

Abstract: Described examples include DC to DC converters and systems with switching circuitry formed by four series-connected switches, inductors connected between the ends of the switching circuitry and corresponding output nodes, and with a flying capacitor coupled across interior switches of the switching circuitry and a second capacitor coupled across the ends of the switching circuitry. A control circuit operates the switching circuit to control a voltage signal across the output nodes using a first clock signal and a phase shifted second clock signal to reduce output ripple current and enhance converter efficiency using valley current control. The output inductors are wound on a common core in certain examples.
