AMA
28V Input, Dual Output
The AMA28XXD series of DC-DC converter modules
has been specifically designed for operation in
moderate radiation environments supplementing the
higher radiation performance available in the
International Rectifier 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
AMA28XXD Series.
The AMA28XXD has been designed for high density
using chip and wire hybrid technology that complies
with the class H requirements of MIL-PRF-38534.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DSCC
qualified processes. For available screening options,
refer to device screening table in the data sheet.
Applicable generic lot qualification test data including
radiation performance can be made available on
request. Variations to the standard screening can be
accomodated. Consult IR San Jose for special
requirements.
AMA28XXD SERIES
The physical configuration of the AMA28XXD 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.
International Rectifier’s rugged ceramic seal pins are
used exclusively in the package thereby assuring long
term hermeticity.
