AMF28XXD SERIES
28V Input, Dual Output
Description
The AMF28XXD series of DC/DC converter modules
has been specifically designed for operation in moder-
ate radiation environments supplementing the higher
radiation performance available in the Advanced Ana-
log ART2815T converter series. Environments pre-
sented 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 perfor-
mance will be optimally served by the AMF28XXD se-
ries.
The physical configuration of the AMF28XXD 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 mechani-
cal security than traditional packages. Advanced
Analog’s rugged ceramic seal pins are used exclusively
in the package thereby assuring long term hermeticity.
The AMF28XXD has been designed for high density
using chip and wire hybrid technology that complies
with the class H requirements of MIL-PRF-38534. Fin-
ished product are fabricated in a facility fully qualified
to MIL-PRF-38534. The standard processing adopted
for the AMF28XXD meets the requirements of MIL-PRF-
38534 for class H but with enhanced screening steps
and includes element evaluation. Applicable generic
lot qualification test data including radiation perfor-
mance can be made available on request. Consult
Advanced Analog for special requirements.
