Abstract
A system includes a single-inductor-multiple-out (SIMO) converter that includes a plurality of output channels, each channel comprising a load, and integrating circuitry in communication with the output channels. The integrated circuitry may be configured to output a signal indicative of a time-accumulated average amount of current drawn through the loads over a sample period. The signal may be used to compare the average current drawn through the output channel with a desired current draw, and to determine whether to change one or more timing parameters used to control the current flow through the SIMO converter.
