PD - 94687A
RADIATION TOLERANT
DC/DC CONVERTERS
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 AMA28XXS has been designed for high density
using chip and wire hybrid technology that complies
with the class H requirements of MIL-PRF-38534. 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. Advanced Analog’s
rugged 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.
Finished product will be fabricated in a facility fully
qualified to MIL-PRF-38534. The standard processing
adopted for the AMA28XXS 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 performance can be made available on
request. Variations to the standard screening can be
accommodated. Consult IR Santa Clara for special
requirements.
