  • Single-inductor multiple-output (SIMO) converter and control method of SIMO converter
    Patent number: 11329557
    Abstract: A single-inductor multiple-output (SIMO) converter includes a converter configured to provide respective voltages of a plurality of channels with a single inductor and a control logic configured to control switches of the converter based on clocks corresponding to the plurality of channels, wherein the control logic is configured to compare an output voltage of a selected channel of the plurality of channels that corresponds to a control target to a reference voltage of the selected channel based on a clock of the selected channel and operate in one of a first mode that adaptively adjusts a number of times that a pulse triggering a power transfer to the channel is generated, and a second mode that blocks a generation of the pulse.
