1. An external battery, comprising:
- a battery;
a charger that supplies, to the battery, external power supplied from an adaptor to an input stage;
a DC-DC converter that converts an output voltage of the battery into a voltage having an amplitude different from that of the output voltage, and transmits the converted voltage to an output stage;
a main controller (MC) that senses a discharge overcurrent of the battery using an output current of the DC-DC converter; and
a switch between the battery and the DC-DC converter, the switch being controlled by the MC.

Abstract
An external battery includes a battery, a charger, a DC-DC conversion, a main controller (MC), and a switch. The charger supplies, to the battery, external power supplied from an adaptor to an input stage. The DC-DC converter converts output voltage of the battery into voltage having an amplitude different from that of the output voltage and transmits the converted voltage to an output stage. The MC senses discharge overcurrent of the battery using an output current of the DC-DC converter. The switch is controlled by the MC and is between the battery and the DC-DC converter.
