ARA2812S Datasheet | Micross

Description The ARA Series of DC-DC converters are low power radiation hardened, high reliability devices designed for radiation environments such as those encountered by geostationary earth orbit satellites, deep space probes and munication systems. Features include small size, high efficiency, low weight and a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical shock, and vibration. Extensive documentation including Radiation Test report, Thermal Analysis, Stress Analysis and MTBF are available. The ARA Series converters incorporate a fixed frequency fly back topology with magnetic feedback. All models include an external inhibit port. They are encased in a hermetic 1.075" x 1.075" x 0.31” Al Si package and weigh less than 13 grams. The package utilizes rugged ceramic feed-through copper core pins and is hermetically sealed using laser welding. Environmental screening includes temperature cycling, constant acceleration, fine and gross leak, and burn-in as specified by MIL-PRF-38534 for class K hybrids. Non-flight versions of the ARA Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be acmodated.
