PD-94529E
HYBRID - HIGH RELIABILITY
RADIATION HARDENED
DC/DC CONVERTER
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 specification. Many of the best
circuit design features characterizing the International
Rectifier 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 hermeticity
is assured through use of parallel seam welded lid
attachment along with International Rectifier’s 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 DSCC qualified
processes. For available screening options, refer to
device screening table in the data sheet.
