CONTROL METHOD AND CONTROLLER FOR SIMO SWITCHING CONVERTERS

There is described a method of controlling a single inductor multiple output, SIMO, switching converter, the method comprising (a) counting, for each output of the multiple outputs of the SIMO switching converter, a period of time during which an output voltage at the respective output is below a corresponding individual threshold value, (b) identifying that output among the multiple outputs of the SIMO switching converter for which the counted period of time is longest, and (c) connecting the identified output to the single inductor of the SIMO switching converter to supply current from the single inductor of the SIMO switching converter to the identified output. Furthermore, a corresponding controller is described.
