Foundry GlobalFoundries has acquired an IP portfolio of power GaN technology and staff from Tagore Technology in the US for an undisclosed sum.

Tagore Technology, set up in 2011, has design centres in Arlington Heights, Illinois,  and in Kolkata, India, and power staff from both will join GF. The company is continuing to sell its GaN RF power amplifiers and switches.

“We are committed to being the foundation of our customers’ power applications today and for decades to come,” said Niels Anderskouv, chief business officer at GF. “With this acquisition, GF takes another step toward accelerating the availability of GaN and empowering our customers to build the next generation of power management solutions that will reshape the future of mobility, connectivity and intelligence.”

“The accelerating demand for more power efficient semiconductors is dramatically increasing, and Tagore has been at the forefront of developing disruptive solutions using GaN technology for a wide range of power devices,” said Amitava Das, co-founder and chief operating officer of Tagore Technology. “The team and I are excited to join GlobalFoundries to increase our focus on market-leading IP that will help address power design challenges and support the continued evolution of automotive, industrial and AI datacentre power delivery systems.”

In February 2024, GF was awarded $1.5 billion in direct funding under the U.S. CHIPS and Science Act, part of that investment is targeted towards enabling the high-volume manufacturing of critical technologies including GaN to securely produce more essential chips.

Combining this manufacturing capacity with the technical know-how of the Tagore team means GF can offer GaN to customers developing power chips for AI system efficiency, especially in edge or IoT devices, where reduced power consumption is critical.

“GlobalFoundries is at the forefront of technological advancements. With Tagore Technology joining the GF India team, we will further enhance our tech capabilities, particularly in emerging areas like GaN,” said Jitendra Chaddah, vice president and India country head at GF. “I welcome the Tagore team to GF, and I am excited about the work we will do as we continue to grow and strengthen our engineering capabilities together.”

Also in February, Tagore announced a partnership with Inventchip to introduce a new compact 500 W power supply reference design with a Totem Pole PFC front-end and an LLC back-end.
The 48V reference design uses Tagore’s TP44100SG (90mOhm) and Inventchip’s CCM Totem Pole controller IC IVC1102/1104 in the front-end PFC section and is aimed at eBike, adapter, server, power tools charger, and telecommunication power supplies with 96.7% peak efficiency..
“Implementation of CCM Totem Pole PFC in a compact footprint is non-trivial. Tagore and Inventchip teams worked collaboratively to develop a compact, robust, and low-cost solution,” said Dhaval Dalal, system architect at Tagore Technology.
“Tagore team is ready to support customers worldwide to implement this new CCM Totem Pole PFC solution in a compact footprint using Tagore’s GaN and Inventchip’s Totem Pole PFC controller,” said Gary Huang, Head of Business Development for Tagore.;
