Unlimited Overvoltage Protection In harsh industrial, automotive and military applications, systems must operate reliably through severe overvoltage events. ® The LTC 4366’s adjustable floating topology is capable of extremely high voltages; the operational upper voltage is limited only by MOSFET ratings. During high voltage transient events, the LTC4366 clamps the output to a user-defined voltage, while the fault timer ensures safe shutdown of the MOSFET if the fault persists.
