Features

AMF

28V Input, Dual Output

The AMF28XXD 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

tableinthedata sheet. Applicable generic lot qualification

test data including radiation performance can be made

available on request. Consult IR Santa Clara for special

requirements.

AMF28XXD SERIES

The AMF28XXD 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

AMF28XXD series.

The physical configuration of the AMF28XXD 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.
