ADVANCE PRODUCT DESCRIPTION
AMF2800 Series
Radiation Tolerant
DC/DC Converters
DESCRIPTION
The AMF2800 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 AMF2800 series.
The physical configuration of the AMF2800 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 AMF2800 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 MILPRF-38534. The standard processing adopted for
the AMF2805S is similar to the requirements of MILPRF-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.
