Navitas’ GaNFast power ICs enable 300W adapter in NVIDIA’s ACE reference design for world’s fastest laptop

Navitas Semiconductor Inc of El Segundo, CA, USA says that its power technology is enabling the highest-density power adapter for the world’s fastest laptop – the Asus ProArt StudioBook One. An NVIDIA RTX Studio system, the ProArt One is the first laptop to feature the NVIDIA Quadro RTX 6000 GPU and is based on NVIDIA’s ACE reference architecture.

Founded in 2014, Navitas introduced what it claimed to be the first commercial GaN power ICs. The firm says that its proprietary ‘AllGaN’ process design kit (PDK) monolithically integrates GaN power field-effect transistors (FETs) with GaN logic and analog circuits, enabling faster charging, higher power density and greater energy savings for mobile, consumer, enterprise, eMobility and new energy markets.

Developed in collaboration with NVIDIA, the new 300W AC-DC adapter design exploits the high-speed power-conversion technology of Navitas’ GaNFast power ICs to create a powerful yet lightweight and small-size mobile charger.

“Creatives and other professionals demand the highest computing performance with extreme mobility,” says Navitas’ CEO Gene Sheridan. “Navitas’ dedicated technologists worked alongside the NVIDIA engineering design team to address this challenge as part of the NVIDIA ACE reference design, delivering a 300W laptop adapter in half the size of traditional adapters,” he adds.

“The high-speed performance of the Navitas GaNFast power ICs is a perfect match for the high-speed NVIDIA Quadro RTX 6000 GPU in the ProArt StudioBook One,” comments NVIDIA’s director of engineering Gabriele Gorla. The result is a laptop with 16.3 TFLOPs of compute performance powered by a mobile adapter that fits in the palm of your hand.

The power adapter uses highly integrated, speed-optimized, next-generation GaN technology that replaces traditional, slow discrete silicon components, and enables the adapter to utilize high-frequency, soft-switching techniques in both power factor correction (PFC) and downstream DC-DC stages. High-frequency, high-efficiency switching shrinks the size, weight and cost of passive components and heatsinks. Navitas says that its GaNFast power ICs enable a new generation of fast-charging mobile adapters for smartphones, tablets and laptops from 27W to 300W+.
