Abstract: Disclosed examples include inverting buck-boost DC-DC converter circuits with a switching circuit to alternate between first and second buck mode phases for buck operation in a first mode, including connecting an inductor and a capacitor in series between an input node and a reference node to charge the inductor and the capacitor in the first buck mode phase, and connecting the inductor and the capacitor in parallel between an output node and the reference node to discharge the inductor and the capacitor to the output node. For boost operation in a second mode, the switching circuit alternates between connecting the inductor and the capacitor in series between the input node and the reference node to discharge the inductor and charge the capacitor in a first boost mode phase, and connecting the inductor between the input node and the reference node to charge the inductor and connecting the capacitor between the first output node and the reference node to discharge the capacitor to deliver power to the output node in a second boost mode phase.

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.
