Inverting single-inductor multiple-output (SIMO) DC-DC converters

A power converter comprising:

• an input switch coupled between a supply terminal and a switching input node;
• a capacitor coupled between the switching input node and a switching multiple output node;
• a discharge switch coupled between the switching input node and a fixed voltage node;
• an inductor coupled to the input switch through the capacitor and coupled between the switching multiple output node and the fixed voltage node;
• a plurality of output switches coupled between the switching multiple output node and a corresponding one of a plurality of output terminals;
• and
• a converter controller having a plurality of switch control outputs coupled to corresponding ones of an input switching control terminal, a discharge switching control terminal, and an output switching control terminal of each of the plurality of output switches, wherein the converter controller is configured to generate switching signals for the input switch, the discharge switch, and the plurality of output switches to generate individual output voltages at corresponding ones of the plurality of output terminals.
