Hybrid - High Power
Radiation Hardened
DC/DC Converter
DESCRIPTION
FEATURES
The ARP Series of DC/DC converters is designed
specifically for use in the hostile radiation
environments characteristic of space and weapon
systems. The high level of radiation tolerance
inherent in the ARP design is the result of
extensive research, thorough analysis and testing
and of careful component specification. Designed
to supplement the single, dual and triple output
configurations provided by the ART and ARH series
of converters, the ARP circuit is for applications
requiring higher output power while providing the
design and performance features incorporated in
those product lines. Capable of uniformly 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 encountered in space.
The ARP converters are hermetically sealed in a
rugged, low profile package utilizing copper core
input and output pins to minimize resistive DC
losses. Long term hermeticity is assured through
use of parallel seam welded lid attachment along
with Lambda Advanced Analog's rugged ceramic
pin-to-package seal. Axial orientation of the leads
facilitates preferred bulkhead mounting orientation
of the converter to the principal heat-dissipating
surface.
Manufactured in a facility fully qualified to MIL-
PRF-38534, these converters are fabricated
utilizing DESC qualified processes, and are
compliant to Class H while being fully processed to
the requirements of Class K. Complete QCI testing
has been completed including Group C life test.
Variations in electrical, mechanical and screening
specifications can be accommodated. Contact
