Low Voltage, High Reliability Radiation Hardened DC-DC Converter

The program addresses a central issue of developing rad-hard high power / high power density power supplies for interceptor components, specifically meeting the MDA need for new cost-effective Hi-Rel supply technology that can support NGI component higher power needs and can support legacy missile (power processor) upgrades. Centered around rad-hard ASIC technology, these power supplies will provide primary power to high power / low voltage interceptor processors and simultaneously provide low power to secondary components. The design approach emphasizes a careful trade-off between SWaP-C issues and radiation tolerance issues as to assure that the end article is very compact while also being radiation tolerant (prompt dose, SEE/SEU immunity, TID, Neutron). The design will provide high efficiency for supplying power for projected interceptor electrical loads. Phase II will undertake the design of a rad-hard high power point-of-load (POL) converter that incorporates beneficial enhancements of our rad-hard ASIC technology. This will include a RHBD cycle to incorporate these enhancements into an upgrade of the existing ASIC devices that were driven by the outcomes of the Phase I program. The resulting power modules will be capable of operating at typical battery voltages and delivering isolated low voltage (3.3V) high power (100W) outputs.
