Abstract
A driving circuit includes a first switching element operating in a turned-on state or a turned-off state depending on a control voltage; a second switching element operating complementarily to the first switching element depending on the control voltage; a constant voltage circuit unit turning on depending on a source-gate voltage of the first switching element to maintain a constant voltage; a current adjusting circuit operating in a turned-on state or a turned-off state depending on the control voltage, and adjusting an operating current flowing to a ground depending on a current control signal in the turned-on state of the current adjusting circuit; a current control circuit controlling the operating current by providing the current control signal to the current adjusting circuit in a turned-on state of the constant voltage circuit unit; and a signal transfer circuit providing the control voltage to a gate of the second switching element.
