The R-78C9.0-1.0 is a 1-output Non-isolated Switching Regulator with non standard output voltage and wide input range. The R-78Cxx-1.0 series high efficiency regulator is ideally suited to replace 1A 78xx linear regulators and is pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat and the high input voltage is an useful feature.
