HYBRID - HIGH RELIABILITY

RADIATION HARDENED

DC/DC CONVERTER

ART28XXT SERIES

Description

Features

ART

28V Input, Triple Output

The ART Series of three output DC/DC converters are

designed specifically for use in the hostile radiation

environments characteristic of space and weapon

systems. The extremely high level of radiation tolerance

inherent in the ART design is the culmination of

extensive research, thorough analysis and testing and

of careful component specification. Many of the best

circuit design features characterizing the International

Rectifier standard product line were adapted for

incorporation into the ART topology.

Capable of

uniformly high performance over long term exposures

in radiation intense environments, this series sets the

standard for distributed power systems demanding high

performance and reliability.

The ART converters are hermetically sealed in a

rugged, low profile package utilizing copper core pins

to minimize resistive DC losses. Long-term hermeticity

is assured through use of parallel seam welded lid

attachment along with International Rectifier’s rugged

ceramic pin-to-package seal. Axial orientation of the

leads facilitates preferred bulkhead mounting to the

principal heat-dissipating surface.
