ABSTRACT:
An electronic device includes electronic components, including: a power switching unit to output a power switching signal; a first power input unit to receive first power from one of a plurality of external power devices; a second power input unit to receive second power from one of the external power devices; a power converting unit to convert the first power received through the first power input unit into driving power having a voltage level to drive each electronic component, and to supply the driving power to each electronic component; and a power management unit to control the power converting unit to be enabled when the second power is input through the second power input unit, and control whether the power converting unit is enabled corresponding to the power switching signal from the power switching unit, when the second power is not input through the second power input unit.
