PURPOSE: A DC-DC converter is provided to show high efficiency with a small size by reducing the inductor number, by implementing two coils in one core to reduce the conduction loss. CONSTITUTION: A primary side core(110) includes a first side unit, a center unit and a second side unit in the primary side and is formed in a letter E shape. A secondary side core(120) includes the first side unit, the center unit and the second side unit in the secondary side and is formed in the letter E shape. The first side unit, the center unit and the second side unit are formed correspondingly to the primary side core. A first winding unit is wound to supply the primary voltage to the primary side core. A second winding unit is wound by plurality number to output the secondary voltage to the secondary side core.
