HYBRID-HIGH RELIABILITY 1MEGA-RAD HARDENED DC-DC CONVERTER PD-94530C ARM28XXT SERIES 28V Input, Triple Output   Description The ARM Series of three output DC-DC converters are designed specifically for use in the high-dose radiation environments encountered during deep space planetary missions. The extremely high level of radiation tolerance inherent in the ARM design is assured as a result of extensive research, thorough analysis and testing, careful selection of components and lot verification testing of finished hybrids. Many of the best circuit design features characterizing earlier IR HiRel products have been incorporated into the ARM topology. Capable of uniformly high performance through long term exposures in radiation intense environments, this series sets the standard for distributed power systems demanding high performance and reliability. The ARM converters are hermetically sealed in a rugged, low profile package utilizing copper core pins to minimize resistive DC losses. Long-term hermetically is assured through use of parallel seam welded lid attachment along with IR HiRel rugged ceramic pin-to-package seal. Axial lead orientation facilitates preferred bulkhead mounting to the principal heat-dissipating surface. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are fabricated utilizing DLA Land and Maritime qualified processes. For available screening options, refer to device screening table in the data sheet. Variations in electrical, mechanical and screening specifications can be accommodated.
