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-PRF-
38534, 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. Contact IR HiRel San Jose for special
requirements.
