Rad-Hard ASIC-Controlled GaN-Based Multichannel POL Converter

QorTek is proposing to design, develop, and demonstrate a rad-hard ASIC-controlled GaN-based multichannel POL Converter to significantly reduce size/weight costs by utilizing high frequency, rad-hard GaN switching technology (which miniaturizes magnetics) and incorporating key control features onto a custom controller ASIC which will eliminate the need for additional large ICs to perform functions such as power sequencing. Each channel will comprise selectable 0.9V to 3.3V outputs of a high-performance synchronous buck converter supplying 10A. We plan to develop a multichannel rad-hard ASIC controller/modulator that is a follow-on to our existing single channel rad-hard ASIC controller/modulator.

Much of the development aims at supplying NASA and the space community with rad-hard multichannel POL regulators providing the very tight regulated voltages needed for on-board FPGAs aimed at beyond LEO missions. Specific targets are NASA New Frontiers missions such as LOP-G cislunar Orbiter/Surface Exploration/Surface Habitat following onto Mars habitat missions that will probably employ a combination of radio isotope (nuclear fission) and solar based power supplies. Another prime target is beyond LEO deployed SmallSat/CubeSat platforms.

Proposed Hi-Rel versions of the multi-output POL regulator and associated multichannel ASIC will find ready markets in military underwater and land systems, As commercial and military aircraft switch from mechanical and analog systems, to "more-electric" configurations they will have increasing POL needs to meet aircraft secondary power, power converters and digital control electronics needs.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
