PURPOSE: A switch driving circuit is provided to change a control signal level based on a reference voltage by removing the direct component of the control signal. CONSTITUTION: A switching driving part(300) operates a switch. A switching control part(100) outputs a switching control signal for the control of the switching operation. A coupling capacitor is connected between the switching driving part and the switching control part. The coupling capacitor eliminates the direct-current component of the switching control signal. The switch driving part switches the switch according to a first power voltage and a driving control voltage. |
