PURPOSE: An apparatus for supplying power is provided to eliminate the noise components of remained load due to the drive of a direct current/direct current converter by forming a filtering part. CONSTITUTION: A first direct current voltage supplying part(102) supplies a first direct current voltage. A control integrated circuit(104) is in electric connection with the first direct current voltage supplying part. The control integrated circuit controls the pulse width of the first direct current voltage. A second direct current voltage supplying part(106) supplies a second direct current voltage to a load. A filtering part eliminates the noise components of the load which is remained by the drive of the control integrated circuit. A feed-back part(110) supplies a fed-back signal from the load to the control integrated circuit. |
