These converters feature high reliability and are designed for extended operation in moderate radiation environments. They are designed to operate without performance or power de-rating under the temperature extremes of -55°C to +125°C. The mechanical design has been characterized and qualified to absorb the mechanical shock and vibration normally encountered during launch and is suitable for low Earth orbit (LEO) satellites and launch vehicles.

Targeted for point-of-load regulation for power systems, they feature hybrid assembly technology, to minimize size and weight. The products are available in the most common input voltage of 28V, with standard output voltages of 3.3V, 5V, 12V, and 15V for single output models, and ± 5V, ± 12V, and ± 15V for dual-output models. They include an input EMI filter that is capable of meeting the conducted emissions and conducted susceptibility requirements of MIL-STD-461C.

All components are stress de-rated to meet the requirements of MIL-STD-975, MIL-STD-1547, and GSFC PPL-21. Radiation test data, which includes TID, SEE, neutron, and prompt dose, are available upon request.
