Description

The ARM Series of three output DC/DC converters are designed specifically for use in the high-dose radiation environments encountered during deep space planetary missions. The extremely high level of radiation tolerance inherent in the ARM design is assured as a result of extensive research, thorough analysis and testing, careful selection of components and lot verification testing of finished hybrids. Many of the best circuit design features characterizing earlier International Rectifier products have been incorporated into the ARM topology. Capable of uniformly high performance through long term exposures in radiation intense environments, this series sets the standard for distributed power systems demanding high performance and reliability.
