HYBRID-HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
PD-94687G
AMA28XXS SERIES
28V Input, Single Output
Description
The AMA28XXS Series of DC-DC converter module has
been specifically designed for operation in moderate radiation
environments supplementing the higher radiation performance
available in the IR HiRel ART2815T converter series. 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 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 Rectifier’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. Manufactured in a
facility fully qualified to MIL-PRF-38534, these converters
are fabricated utilizing DLA qualified processes. For availa-
ble 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 HiRel San Jose for special requirements.
