ADVANCE PRODUCT DESCRIPTION
AMR2800 S eries
Radiation T olerant
DC/DC Converters
DESCRIPTION
FEATURES
The AMR2800 series of DC/DC converter modules
has been specifically designed for operation in
moderate radiation environments supplementing the
higher radiation performance available in the
Lambda Advanced Analog ART2815T converter
series. Environments presented to space vehicles
operating in low earth orbits, launch boosters,
orbiting space stations and similar applications
requiring a low power, high performance converter
with moderate radiation hardness performance will
be optimally served by the AMR2800 series.
The physical configuration of the AMR2800 series
permits mounting directly to a heat conduction
surface without the necessity of signal leads
penetrating the heat sink surface. This package
configuration permits greater independence in
mounting and more mechanical security than
traditional packages. Lambda Advanced Analog’s
rugged ceramic seal pins are used exclusively in the
package thereby assuring long term hermeticity.
The AMR2800 has been designed for high density
using chip and wire hybrid technology that complies
with the intent of MIL-PRF-38534. Finished product
will be fabricated in a facility fully qualified to MIL-
PRF-38534. The standard processing adopted for
the AMR2800 series is similar to the requirements
of MIL-PRF-38534 for class H, and includes
element evaluation. Applicable generic lot
