Abstract
Single-input-multiple-output (SIMO) DC-DC converters and SIMO DC-DC converter control circuits are disclosed. An example DC-DC converter control circuit includes a switch controller to control respective switches of a SIMO DC-DC voltage converter that has multiple output circuits. The example control circuit also includes an arbitration circuit that determines a first one of the output circuits to have priority over other ones of the output circuits based on a priority signal, and selects a first output circuit to be charged during a first time slot based on the priority signal and based on first kick signals indicating that the at least two output circuits are to be charged. The control circuit also includes a next kick detector that determines a second one of the output circuits to be charged during a second time slot after the first time slot based on the priority. The control circuit also includes a time slot controller that determines a first time duration of the first time slot based on the determined second one of the output circuits, the arbitration circuit to output a second kick signal to the switch controller to control the switches to charge the first one of the output …
