AMF28XXS SERIES
28V Input, Single Output
ADVANCED ANALOG
RADIATION TOLERANT
DC/DC CONVERTERS
Description
The AMF28XXS 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 ART, ARH and G-Series converters. Environ-
ments 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 hard-
ness performance will be optimally served by the
AMF28XXS Series.

The physical configuration of the AMF28XXS series
permits mounting directly to a heat dissipation 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.
No SEE to LET > 60 MeV-cm2/mg
-55°C to +125°C Operating Range

n
High Power Density
n Fully Isolated - Input to Output and to Case
n Complimentary EMI Filter Available
n Synchronizable From An External Source
n Electrical Performance Similar to
AHF28XXS Series
The AMF28XXS 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 AMF28XXS 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.
