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.
