Navitas Cranks Up the Power with Gallium Nitride

Navitas NV6128

66% more power GaNFast IC takes a bigger bite from the old, slow silicon chip market.

Navitas Semiconductor announced the NV6128, a new high-power 650V/800V-rated GaNFast power IC to address the high-power mobile and consumer power electronics market, and take market share from the old, slow, silicon chip. The 70 mOhm NV6128 represents a 66% increase in current capability, in a small, 6 × 8 mm PQFN package with a proprietary, integrated cooling pad for high-efficiency, high-density power systems.

Gallium nitride (GaN) is a next-generation semiconductor technology that runs up to 20x faster than old, slow silicon (Si), and enables up to 3x more power or 3x faster charging in half the size & weight. GaNFast power ICs integrate GaN power and drive plus protection and control to deliver the simplest, smallest, fastest and now even higher-power performance.

“GaNFast power ICs have been broadly adopted by tier-1 names like Lenovo, Dell, OPPO and Xiaomi for fast-charging mobile adapters up to 200 W, with over 13,000,000 shipped and zero failures,” noted Gene Sheridan, Navitas CEO and co-founder. “With the higher-power NV6128, we extended the effective power range to 500 W for the consumer market and look beyond that to multi-kW data center, eMobility and new energy applications.”

Unlike competing solutions, the NV6128 is rated at 650 V for nominal operation plus a high, 800 V peak capability for robust operation during transient events. As a true power IC, the GaN gate is fully protected and the whole device rated at an industry-leading electrostatic discharge (ESD) specification of 2 kV.

“It’s a night and day comparison,” said Dan Kinzer, Navitas CTO/COO and co-founder. “Compared to current tier-1 OEM laptop adapters using old silicon in traditional diode rectification and boost PFC topologies at 50-70 kHz, the GaNFast NV6128 enables a modern high-speed totem-pole architecture and complete 300 W solutions at over 1.1 W/cc. That’s up to 3x smaller and lighter with existing 200 kHz control. When you crank up the speed to MHz+, you get another major step-increase in power density.”

For power electronics designers, the NV6128 and all the GaNFast power IC family offer easy-to-use, high-speed, high-efficiency solutions for 200-500 W applications such as all-in-one PCs, TVs, game consoles, eMobility chargers (eScooters, eBikes), gaming laptops and more.

Design-support includes detailed datasheets, electrical models (SPICE), and mechanical models (.stp). The NV6128 is in high-volume, mass production and immediately available from Navitas distribution partners, with a low price of $7.85 at 1k units.
