1. An electronic device, comprising:
a battery;
a plurality of capacitors;
a converter configured to receive power from the battery and to charge each of the plurality of capacitors to different voltages based on the power;
a plurality of switches configured to switch a first path and a second path of each of the plurality of capacitors; and
a controller operatively coupled to the battery, the plurality of capacitors, and the plurality of switches,
wherein the controller selects a first switch among the plurality of switches based on a received signal and controls the first switch such that a path of a capacitor connected to the first switch is switched from the first path to the second path,
wherein the first path is a path which electrically connects each of the plurality of capacitors to the converter, and
wherein the second path is a path which electrically connects each of the plurality of capacitors and a power amplifier (PA).
