1. An electronic device comprising:
a battery disposed inside the electronic device;
a printed circuit board (PCB) disposed inside the electronic device;
at least one electronic component disposed on the PCB;
a first buck converter configured to output a first level of voltage that is reduced from a voltage level of the battery, the first buck converter having a first end and a second end, wherein the first end is routed to the battery; and
a second buck converter configured to output a second level of voltage that is reduced from the voltage level of the battery, the second buck converter having a first end and a second end, wherein the first end is configured to selectively connect electrically to the second end of the first buck converter, and the second end is routed to the at least one electronic component, and
when the first end of the second buck converter electrically connects to the second end of the first buck converter, the first buck converter and the second buck converter form a buck booster configured to provide a boosted voltage level from the voltage level of the battery to the at least one electronic component.
