ARE2812S

HIGH RELIABILITY RADIATION HARDENED LOW POWER DC-DC CONVERTER PD-97837C ARE SERIES 28V Input, Single Output Description The ARE 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 communication 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. The ARE Series converters incorporate a fixed frequency flyback 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” AlSi package and weigh less than 15 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 ARE Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be accommodated.
