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.
