Abstract: An apparatus is disclosed for a single-inductor multiple-output (SIMO) power converter with a cross-regulation switch. An example apparatus includes a power source and a SIMO power converter. The SIMO power converter includes an input node coupled to the power source, a first node, a second node, a ground node, and an inductor coupled between the first node and the second node. The single-inductor multiple-output power converter also includes a first switch coupled between the input node and the first node, a second switch coupled between the first node and the ground node, and a cross-regulation switch coupled between the input node and the second node.
