ADVANCE PRODUCT DESCRIPTION
AMA2800 Series
Radiation Tolerant
DC/DC Converters
DESCRIPTION
FEATURES
The AMA2800 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 AMA2800 series.
The physical configuration of the AMA2800 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 AMA2800 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 AMA2805S is similar to the requirements of
MIL-PRF-38534 for class H, and includes element
evaluation. Applicable generic lot qualification test
data including radiation performance can be made
available on request.
Variations to the standard
screening can be accommodated. Consult Lambda
Advanced Analog for special requirements.
