PD-94690D
HYBRID - HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
AMR28XXD SERIES
28V Input, Dual Output
Description
The AMR28XXD 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
AMR28XXD series.
The physical configuration of the AMR28XXD 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.
The AMR28XXD has been designed for high density
using chip and wire hybrid technology that complies
with class H requirement of MIL-PRF-38534.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DLA
Land and Maritime 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 accommodated. Consult IR San
Jose for special requirements.
