650V GaN Power ICs get Production Qualification

February 06, 2017 by Jeff Shepard

Navitas Semiconductor today announced the immediate availability of production qualified iDrive™ GaN Power ICs using the company's proprietary AllGaN™ technology. The NV6131, NV6105 and NV6115 offer a high-efficiency 650V, 160mOhm power FET with increasing integration of digital and analog circuits, leading to ground breaking speed, energy efficiency, power density and reduced system cost. The NV6131 is simply a 650VGaN FET (135mOhm); the NV6105 is a 650VGaN Power IC (160mOhm FET+driver+logic); and the NV6105 is a more complex 650VGaN Power IC (160mOhm FET+driver+logic+regulator). All three devices are delivered in a 5x6mm QFN.

GaN can enable up to 100x higher frequencies than silicon but driving, controlling and protecting such high-speed power devices has been an industry challenge that has limited adoption. By integrating these critical digital and analog circuits monolithically with the GaN power device, these system level problems have been eliminated. Navitas GaN Power ICs with iDrive guarantee optimized and robust performance for any application. A 10x to 100x increase in system operating frequency is combined with higher efficiencies to enable up to a 5x increase in power densities and 20% lower system costs.

“GaN Power ICs, with the monolithic integration of logic, analog and power, represent an industry breakthrough that will change the landscape of power electronics as we know it”, explained Navitas CEO Gene Sheridan. “By integrating all gate-drive-related circuitry, virtually all frequency-related power losses are eliminated, opening the door to significant frequency and efficiency gains. We anticipate a major upgrade cycle in mobile fast chargers, thin TVs, high-efficiency data centers, LED lighting, solar and electric vehicle markets as this new high-speed revolution in power electronics gets underway”, Sheridan added.

“The Center for Power Electronics Systems (CPES) at Virginia Tech has been pioneering the advancement of high-frequency power systems for over three decades” explains Dr. Fred Lee, the university’s distinguished and globally recognized professor. “The invention of GaN power ICs represents a major industry breakthrough and is a critical ingredient to make high-speed, high-efficiency power systems a reality. This is an exciting time for the power industry”, Lee concluded.

The NV6131, NV6105 & NV6115 (in 5x6mm QFN) are available immediately to qualified partners. Navitas will demonstrate the new NV61xx series in a demonstration suite at the Applied Power Electronics Conference (APEC) March 26th – 30th, 2017 in Tampa, Florida, USA.
