Abstract
Provided is a single inductor multiple output (SIMO) direct current-to-direct current (DC/DC) converter that may perform DC/DC conversion by transferring, to output nodes, input current that is input and thereby stored in a single inductor. An output selection unit of the SIMO DC/DC converter may select, from output nodes, a first output node to be supplied with current from a driving unit, and provide output voltage of the first output node and reference voltage of the first output node to a hysteresis comparison unit. The hysteresis comparison unit may control on-time and/or inductor peak current by determining whether the output voltage of the first output node is higher than the reference voltage of the first output node by at least a first threshold, and whether the output voltage of the first output voltage is lower than the reference voltage of the first output voltage by at least a second threshold.
