Abstract:
An example electronic device including a power supply circuit may include a battery; a display module including a display panel; a regulator; a power supply circuit configured to: based on an input voltage of the battery, provide a first voltage and a second voltage to the display module, and provide a third voltage to the regulator; and a switch control circuit configured to: control a switching operation of the power supply circuit, wherein the power supply circuit includes: a first power circuit and a second power circuit, wherein the first power circuit includes multiple switch elements, a first capacitor, a second capacitor, a third capacitor, and a first inductor, and is configured to: for a first time interval, based on a drive signal of the switch control circuit, charge the first capacitor and the second capacitor, based on a current of the first inductor and discharge the third capacitor to provide a first output current to the display module, and for a second time interval, based on a drive signal of the switch control circuit, charge the third capacitor and discharge the first capacitor and the second capacitor to provide the first output current and a second output current to the display module, and wherein the second power circuit is configured to: convert a voltage level of the input voltage of the battery to provide a second voltage to the display module.
