Navitas GaN ICs upgraded from 650V to 700V for continuous operation
Gallium nitride (GaN) power integrated circuit firm Navitas Semiconductor of El Segundo, CA, USA and Dublin, Ireland says that its GaNFast power ICs with GaNSense technology have been upgraded to increase efficiency, power density and access additional fast-charger markets.
GaN runs up to 20x faster than silicon and enables up to 3x more power, 40% energy savings and 3x faster charging in half the size and weight, says Navitas. GaNFast power ICs integrate GaN power and drive plus protection and control to deliver simple, small, fast and efficient performance. Over 30 million GaNFast power ICs have been shipped with zero reported field failures.
The ‘voltage rating’ of NV613x and NV615x GaNFast power ICs with GaNSense has been upgraded from 650V to 700V for continuous operation, and is rated at 800V for transient conditions. Increased voltage rating enables more efficient power transformer circuit designs, and higher capabilities for areas of the world with unreliable, widely varying power grids with extreme voltage spikes, says the firm. Autonomous system-level monitoring and reaction ensures ‘detect and protect’ within 30ns – 10x faster than for discrete implementations.
“GaNFast power ICs already deliver the highest reliability and highest performance in the mobile fast-charger market,” claims co-founder & chief operating officer/chief technology officer Dan Kinzer. “Navitas’ engineering, quality and applications teams continue to deliver leading-edge, next-generation technology with a proven, data-driven approach that enables customers to innovate aggressively in power conversion and fast-charger design – and to access expanded markets in more areas of our world,” he adds.
Updated datasheets and reliability reports are available immediately to customers and design partners under non-disclosure agreement (NDA).
