IR – Hi-Rel Radiation Hardened Low Power DC/DC Converter

Description

The ARE Series of DC-DC converters are low power radiation hardened, high reliability devices designed for radiation IR- ARE Seriesenvironments 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. All components are fully de-rated to meet the requirements of MIL-STD-975, MIL-STD-1547 and NASA EEE-INST-002. Extensive documentation including Radiation Susceptibility, Thermal Analysis, Stress Analysis and MTBF are available.

The ARE Series converters incorporate a fixed frequency flyback topology with magnetic feedback and an internal EMI filter utilizing large multilayer ceramic capacitors processed per MIL-PRF-49470 for improved reliability. All models include an external inhibit port. They are encased in a hermetic 1.20″ x 1.20″ 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.
