Low Voltage, High Reliability Radiation Hardened DC-DC Converter

The proposed program will result in a novel design for a Hi-Rel, rad-hard low voltage power supply that can operate off space bus as to provide on-board power conversion for processors such as Field Programmable Gate Arrays (FPGAs). Based on QorTek’s recent introduction of the custom ASIC (QT-IC-R-1101-E) rad-hard controller/modulator chip the novel dc-dc converter will be very high efficiency and will greatly increase radiation hardness in a very compact design that meets or exceeds the target radiation tolerances. The availability of the radiation tolerant QT-IC-R-1101-E and overlapping prior rad-hard converter developments will greatly reduce the cost, size, and optimize performance of the proposed multioutput converter. The program will exit Phase I with tested hardware and a clear path to demonstrate and test radiation tolerances as to result in a very commercially competitive product available to the military space community.
