Navitas Semiconductor, an industry leader in gallium nitride (GaN) power integrated circuits (ICs) has announced the acquisition of VDD Tech, the creator of advanced digital isolators for next-generation power conversion.
Advanced digital-isolation techniques are essential in delivering size, weight, and system-cost improvements in high-power markets such as consumer, motor drive, solar, data center, and EV. VDD Tech’s proprietary modulation technique enables stable, reliable, efficient power conversion at MHz+ switching speeds.
Proprietary dV/dt sensing, blanking, and refresh technologies enable an unprecedented combination of very-high-voltage-isolation capability with the highest frequency of operation requiring 5-10x higher dV/dt immunity than legacy Silicon. Low isolation capacitance (<0.5 pF) and innovative, robust modulation deliver low-jitter digital communication for isolated-driver control and analog-sensing feedback. A minimum of 200 V/ns Common-Mode Transient Immunity (CMTI) is uniquely guaranteed across all temperature and operating conditions.
VDD Tech was founded in Mont-Saint-Guibert, Belgium, by Vincent Dessard, quickly joined by Aimad Saib, each of them holding a doctorate and 15+ years of experience in analog/mixed-mode IC research and development. Dessard and Saib have taken leading roles in Navitas’ advanced R&D teams.
“It’s exciting to see two breakthrough technologies-optimized digital-isolators and GaN power ICs- combine to deliver such leading-edge, high-power solutions,” said Dessard, adding “High-speed and high-reliability are the critical factors to accelerate wide-band-gap-semiconductor adoption over legacy silicon-chips, and we’re very excited to be a catalyst in this once-in-a-generation revolution, with new, high-power products launching in 2023.”
“VDD Tech’s isolation technology is a key part of our growing power-and-control integration strategy, creating an additional $1B/yr market opportunity,” said Gene Sheridan, Navitas CEO, and co-founder. “We continue to research and review new technologies that we could add to Navitas’ core strengths, and deliver significant CO2 emission-reduction benefits as we continue our mission to 'Electrify Our World'”.
