Navitas’ GaNFast power ICs used in Lenovo’s Xiaoxin 105W and Legion C170W fast chargers
Gallium nitride (GaN) power IC and silicon carbide (SiC) technology firm Navitas Semiconductor of Torrance, CA, USA says that its GaNFast power ICs have been selected to lead Lenovo’s latest GaN technology chargers: the Xiaoxin 105W and the Legion C170W, respectively designed for daily travel and gaming power.
The Xiaoxin 105W GaN charger outputs 105W of power and is equipped with three ports (2C1A) supporting multiple protocols, achieving the charging needs of various devices simultaneously. At only 206g, the 105W fast charger is 41% lighter than a typical 100W computer adapter and takes only 34 minutes to charge the Xiaoxin 16 Pro to 50%. The Navitas NV6138 GaNFast power IC with GaNSense technology is at the heart of the high-frequency flyback topology design, providing a stable, durable and efficient charging experience.
The Legion C170W GaN charger delivers 170W of continuous power through a single port to meet the high-power demands of gaming devices. At only 245g, it is 78% lighter than the Legion Y9000P’s original in-box charger and can charge up to two times faster than the Legion C140W charger. The Navitas NV6136 GaNFast power IC with GaNSense technology is used in the power factor correction (PFC) stage, featuring loss-less current sensing and six times faster short-circuit protection than competing solutions, it is claimed, delivering cooler operation, superior efficiency, reliability, and power density.
Lenovo’s long-term collaboration with Navitas has brought a series of fast chargers to the market and played a role in raising market awareness by showcasing the benefits of GaN technology. At the Lenovo YOGA CC65 dual-port GaN charger launch event in 2021, Navitas’ 6-inch GaN wafer and GaNFast power ICs were publicly showcased for the first time. In terms of gaming products, Navitas collaborated with Lenovo to create a 90W charger for the Lenovo Legion Pro Gaming Phone and the C135W GaN charger for the Legion 5 and 5 Pro Gen 7 laptops. For lightweight travel, Lenovo developed a series of compact, lightweight powerful GaN chargers using Navitas technology, including the compact Thinkplus ‘lipstick’ and the ultra-thin Thinkbook ‘biscuit’ charger.
“The successful application of Navitas’ GaNFast technology continuously reduces the size and weight of chargers, highly increasing efficiency, bringing convenience to consumers, while contributing to carbon reduction,” says Elon Chen, product manager of Consumer Business for Lenovo Group China.
“Powerland is very pleased to collaborate with Navitas again to create two high-performance and lightweight GaN chargers for Lenovo,” says Dr Wang Chuanyun, VP of R&D for Powerland Group. “Powerland is dedicated to pushing the envelope of technology to build leading power products for our clients. Efficient, reliable, and easy-to-use GaNFast power ICs are crucial to realize that,” he adds.
“Navitas is very honored to enter Lenovo’s supply chain twice in a short period, providing high-efficiency and stable GaNFast fast-charging power into two important Lenovo products,” says Charles Zha, VP & general manager of Navitas China. “By working closely with Powerland, our highly integrated GaNFast technology has enabled Lenovo to continuously achieve leading-edge results in size, performance and reliability of chargers,” he adds. “With innovative laptops like AI PCs on the rise, Navitas predicts a surge in demand for powerful GaNFast charging solutions. Navitas is on a mission to push the limits of gallium nitride technology, empowering global partners like Lenovo to slash energy usage and emissions in charger and adapter production.”
