DC/DC CONVERTER
PD-94687E
AMA28XXS SERIES
28V Input, Single Output
Description
The AMA28XXS 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
AMA28XXS Series.
The physical configuration of the AMA28XXS 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
Rectifiers’srugged ceramic seal pins are used
exclusively in the package thereby assuring long term
hermeticity.

The AMA28XXS 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 accommodated.
Consult IR Santa Clara for special requirements.
