HYBRID-HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
PD-95887C
ARH28XXXXS SERIES
28V Input, Single Output
 
Description
The ARH Series of DC-DC converters has been designed
specifically for use in the hostile environments The high
level of radiation tolerance inherent in the ARH design is
the result of extensive research, thorough analysis and
testing and of careful component specification. Designed
to supplement the triple output configuration provided by
the ART Series, the ARH circuit topology is the follow-on
to the successful ART design and incorporates many of
the design features characterizing that product line. Capable of
uniform high performance over long term exposures in
radiation intense environments, this series expands the
standard for distributed power systems demanding high
performance and reliability in the harsh environments.
The ARH converters are hermetically sealed in a rugged,
low profile package utilizing copper core input and output
pins to minimize resistive DC losses. Long-term hermetically
is assured through use of parallel seam welded lid attachment
along with rugged ceramic pin-to-package seal. Axial orientation
of the leads facilitates preferred bulkhead mounting placing the
converter on 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.
