PROBLEM TO BE SOLVED: To provide a low-voltage high-current power supply device which is small in size and thin in thickness and has a high power conversion efficiency. SOLUTION: A plurality of field effect transistors are attached to output taking-out terminals of a transformer on both the surfaces of the terminals or in arrangement and are connected directly to the terminals. With such a constitution, impedances between power supply components are reduced, and a power conversion efficiency is improved. Further, operation temperatures of the field effect transistors are uniformed to make the characteristics uniform, so that a power supply device component connection method, by which size and thickness of a power supply can be reduced, can be provided.
