Abstract
A system includes a voltage surge protection circuit that receives a source voltage from a source. The voltage surge protection circuit includes a reference circuit to generate a reference voltage based on the source voltage when the source voltage exceeds a clamping voltage and a feedback control circuit to receive the reference voltage and clamp an output voltage to the clamping voltage when the voltage from the source exceeds the clamping voltage. A dynamic resistance of the feedback control circuit is substantially zero.
