A lamp driving inverter protection circuit is provided to reinforce feedback impedance by transmitting a feedback current using a voltage follower. A lamp driving inverter protection circuit includes a transformer(T1), a detection resistor(Rs), a voltage follower(110), a first capacitor(C1), a second capacitor(C2). The transformer supplies power to a load terminal. The detection resistor detects a feedback current outputted from the load terminal. The voltage follower transmits a feedback current signal detected through the detection resistor to a drive for controlling an operation of the lamp driving inverter protection circuit. A side of the first capacitor is coupled to a second side of the transformer. The other side of the first capacitor is coupled to the load terminal. A side of the second capacitor is coupled between a second side of the transformer and the first capacitor. The other side of the second capacitor is coupled to a ground. |
