HYBRID-HIGH RELIABILITY

RADIATION TOLERANT

DC-DC CONVERTER

AMA

AMA28XXD SERIES

Description

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 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 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.

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 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.
