ABSTRACT:
The switch mode power supply includes a switching cell SC controllable cyclically and including only one inductive element L and several individually selectable outputs. During each conduction cycle, a total power level corresponding to the sum of the individual power levels respectively required by all the outputs OUTi during this cycle is injected into the inductive element L, the outputs requiring a non-zero individual power level are selected successively and in a predetermined order that is identical for all the cycles, and, at each selected output, the corresponding individual power level is produced.
