Abstract
Single inductor multiple output (SIMO) switching devices with efficient regulating circuits. The SIMO switching device includes a plurality of time division multiplexing (TDM) switches for switching current through an inductor of the SIMO switching device. The plurality of TDM switches produces a plurality of outputs. The SIMO switching device further includes an error calculation circuit operatively coupled to the plurality of outputs for determining a calculated error from the plurality of outputs; a time slot generation circuit for controlling the plurality of TDM switches according to the calculated error; and a pulse width modulation (PWM) control circuit operatively coupled to the time slot generation circuit for controlling a plurality of PWM switches of a switching stage of the SIMO switching device in a continuous conduction mode (CCM) of operation. The PWM switches are controlled according to the time slots generated by the time slot generation circuit.
