GaN Technology Requirements: Serving the Broadest Medium Voltage Market with the Highest Reliability and Lowest Cost

GaN technology needs to serve the widest variety of markets to be a viable, long-term solution. To advance market adoption today well into tomorrow, GaN technology should then provide high performance with high reliability for low watt markets such as adapters through to Titanium-class power supplies as well as Electric Vehicle solutions (e.g., on-board chargers and DC/DC converters). Drawing on more than a decade of experience developing and supplying GaN technology to various industries, this presentation will detail broad market needs and opportunities as well as how diverse, qualified 650V and 900V product portfolios coupled with demonstrated 1200V devices validate GaN’s market-readiness.
