Switching regulated power supply employing an elongated metallic conductive inductor having a magnetic thin film coating
 An inductor and a switching means are combined in such a way that the storage of the energy in the inductor and the release of the energy stored in the inductor are repeatedly carried out, whereby the released energy is rectified and smoothed to obtain a DC output. The inductor is fabricated from a conductor comprising a wire coated with a thin magnetic film in such a way that the easy axis of said thin magnetic film is extended substantially in the longitudinal direction of the wire. Furthermore, a plurality of inductor and switching element pairs are provided and are switched in different phases, respectively.
