ABSTRACT:
A switching device which can reduce effectively noise that is generated from a charge pump used to generate a drive voltage for driving a plurality of semiconductor switches. In the switching device, the charge pump used to generate the drive voltage for operating the plurality of the semiconductor switches is shared in common by these semiconductor switches, and the plurality of the semiconductor switches can be driven by the drive voltage that is generated by the single charge pump. Due to this structure, the noise to be generated by the charge pump can be controlled to a minimum and the noise interfering into the power line can be removed by a single noise remove circuit, which makes it possible to simplify the structure of the switching device.
