Summary:According to the present invention, in order to control a plurality of power sources in an electronic apparatus, an apparatus for controlling power sources includes: a switching unit for selectively supplying a first power source which is continuously generated or a second power source which is discontinuously generated to a load in the operation of the electronic apparatus; and a control unit for controlling the switching of the switching unit to supply the second power source after the delay of predefined time when the second power source is generated. Also, the control unit controls the switching of the switching unit to supply the first power source without delay when the second power source is exhausted.
