Claim 0:
1. A DC-DC converter comprising:
a converting circuit for converting a power received from the solar power supply;
a sensing circuit including one or more resistors and a sensing switch, and sensing a state of a battery; and
a processor for controlling the sensing switch based on the state of the battery,
wherein the processor determines one of a plurality of modes as a current mode based on the state of the battery, and turns off the sensing switch when the current mode is a sleep mode
wherein the processor determines the current mode as the sleep mode when a remaining amount of the battery is less than or equal to a first value,
wherein the processor determines the current mode as the shutdown mode when the remaining amount of the battery is less than or equal to a second value, and
wherein the second value is smaller than the first value.
