Abstract
A system includes a single-inductor-multiple-out (SIMO) converter that includes storage circuitry in communication with a plurality of output channels, and a controller that is configured to output one or more signals to alternatingly conduct current through the output channels over a plurality of switching cycles. The controller may determine fixed ratios of channel conduction periods between the plurality of output channels and set channel conduction periods for each switching cycle based on the fixed ratios. In addition or alternatively, the controller may determine an arrangement of orders in which to conduct current over the switching cycles. The arrangement may include an order for a current switching cycle that is a reverse order of an order for a previously switching cycle.
