Techniques for controlling single-inductor multiple-output (SIMO) switch mode power supply (SMPS)
By comparing the inductor current with multiple thresholds in a single-inductor multi-output switching mode power supply, and selecting and configuring the SMPS state, the problem of low inductor current regulation efficiency is solved, achieving more efficient voltage regulation and stable output.

Abstract
Certain aspects of this disclosure generally relate to methods and apparatus for operating a switch-mode power supply (SMPS). An example method typically includes comparing a signal representing the amount of current across an inductive element of the SMPS with at least three threshold values, selecting a configuration of the SMPS based on the comparison, and configuring the SMPS based on the selection.
