HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
PD-94529H
ART28XXT SERIES
28V Input, Triple Output
 
Description
The ART Series of three output DC-DC converters are
designed specifically for use in the hostile radiation environments
characteristic of space and weapon systems. The extremely high
level of radiation tolerance inherent in the ART design is
the culmination of extensive research, thorough analysis
and testing and of careful component selection. Many of
the proven circuit design features characterizing the IR
Hirel standard product line were adapted for incorporation into
the ART topology. Capable of uniformly high performance
over long term exposures in radiation intense environments, this
series sets the standard for distributed power systems
demanding high performance and reliability.
The ART 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
orientation of the leads 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.
