Lenovo to partner with FINsix for power adapters

Lenovo GaN FINsix adapter laptop

FINsix Corporation , the high-frequency power electronics design start-up, today announced its partnership with Lenovo, the PC manufacturer, to bring Lenovo’s laptops the smallest ever 65W charger option for ThinkPad laptops.

The two companies have collaborated under a joint development agreement, and Lenovo is set to offer the new charger, dubbed the ThinkPad 65W Adapter, as an option for the new ThinkPad X1 Carbon and X1 Yoga. FINsix and Lenovo will be exhibiting the new charger at CES, the global consumer electronics trade show, January 6-9 in Las Vegas.

FINsix is a company Point The Gap featured in its article about Gallium Nitride and consumer power adapters. It developped a laptop adapter using Resonant LLC converter topology to operate at higher frequency of conversion. This high frequency allows smaller passive components and better efficiency. It’s a technology transferred from RF and Military applications. FINsix was initially created on the campus of MIT, with the objective to power LED with their technology. They reoriented their aim to laptop adapters later, as a more accessible market. These technology will be featured in Point The Gap next market report about GaN devices and applications.

An interesting fact about this technology is that today’s FINsix adapters use Infineon Silicon based devices (CoolMOS and OptiMOS, respectively for high voltage and low voltage sides). But it could become and enabler and a first volume produced system to use Gallium Nitride power electronics devices. The topology fits perfectly the high frequency capabilities of GaN devices. It also compensates the youngness of GaN with the relatively short lifetime needed for a laptop charger.

“Lenovo is constantly searching for partners who have disruptive technologies that can add value to our customers,” said Luis Hernandez, vice president and general manager of Lenovo’s ThinkPad Business Unit. “We are working with FINsix because their power conversion technology is a game-changer. It brings a level of portability that we expect will become the standard of the future.”

Vanessa Green, CEO of FINsix, said,

“We are thrilled to partner with the market leader in personal computers. Lenovo has a strong customer base and this collaboration positions us to scale quickly among corporate customers eager to lighten their load when on the go.”

The ThinkPad 65W Micro Adapter is based on the same high-frequency power technology as FINsix’s first product, the Dart, a 65W aftermarket laptop adapter with a 2.1 amp USB port for simultaneously charging phones, tablets, and other devices. The Dart has been featured in a Kickstarter campaign about 18 months ago. Deliveries have been delayed many times and does not seem to have started yet. It was featured at CES in 2014.
