Features

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 DLA

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.
