Abstract: An electronic device includes a system on chip (SoC) and a power management integrated circuit (PMIC). The SoC includes a plurality of power domains and a dynamic voltage and frequency scaling (DVFS) controller which performs DVFS on the power domains The PMIC includes direct current (DC)-DC converters and a control logic which controls the plurality of DC-DC converters, and each of the DC-DC converters provides a corresponding output voltage to a respective one of the power domains. The control logic designates a target DC-DC converter which provides a target output voltage having a target level as a global DC-DC converter and provides the target output voltage to a power domain corresponding the global DC-DC converter and to at least one first power domain consuming the target output voltage, from among the plurality of power domains, by sharing the target output voltage provided by the global DC-DC converter.
