SWITCHING DEVICE HAVING A GOOD ISOLATION CHARACTERISTIC, METHOD FOR IMPROVING THE ISOLATION CHARACTERISTIC OF A SWITCHING DEVICE

摘要

A switching device having a good isolation characteristic is disclosed. The switching device comprises a switch unit and a control unit, wherein the control unit is connected to a power supply terminal, and connected to the switch unit via a control line and a power line. The control unit comprises a voltage regulator unit that is electrically connected to the power supply terminal and the power line of the switch unit. When the switch unit enters standby mode, the control unit provides an isolation voltage to the switch unit to effectively enhance the isolation characteristic of the switching device in the standby mode.
