Claim 0:
1. An electronic device comprising a power supply circuit, the electronic device comprising:
a battery;
a display module comprising 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 comprises multiple switch elements, a first capacitor, a second capacitor, a third capacitor, and a first inductor, wherein the switch control circuit is configured to control the multiple switch elements to:
for a first time interval, charge the first capacitor and the second capacitor based on at least a part of a current of the first inductor, provide current through a second output port to the display module based on at least a part of the current of the first inductor, and provide current through a first output port to the display module by discharging the third capacitor, and
for a second time interval, charge the third capacitor, provide current through the first output port to the display module based on at least a part of a current of the first inductor, provide current through the first output port to the display module by discharging the first capacitor and the second capacitor, and provide current through the second output port to the display module by discharging the first capacitor.
