    摘要： The present invention provides a switching circuit and an electronic switching component having a switching semiconductor device to perform switching between a conducting state and a non-conducting state of a conducting path to thereby reduce the power loss thereof and a control method thereof. In the present invention, at least two FETs 11 and 12, wherein the FET 11 has a faster switching time and the FET 12 has a lower ON resistance. Active terminals (drains and sources) of the FETs 11 and 12 are connected to each other in parallel. By employing these FETs 11 and 12, the conversion between an ON-state and an OFF-state of the conducting path is performed. In converting from the non-conducting state to the conducting state, the control circuit 13 first turns on the FET 11 and then turns on the FET 12 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof. In converting from the conducting state to the non-conducting state, the control circuit 13 first turns off the FET 12 and then turns off the FET 11 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof.

    摘要： A hybrid integrated circuit device is provided which suppresses lowering of the inductance value of a mounted coil component. A hybrid integrated circuit device according to the present invention has such a structure that a wiring pattern is provided on at least one main face of a substrate, a laid core type coil component is mounted on at least one main surface of the substrate, and a conductor pattern including a ground pattern is provided at least either on a main face opposite to the surface of the substrate upon which the laid core type coil component is mounted or in an interior of the substrate. In particular, the hybrid integrated circuit device has a configuration such that a magnetic flux passing window, having an absence of ground pattern, is provided in an orthographic projection area corresponding to a winding portion of the coil component in the conductor pattern.
