Infineon and Delta strengthen collaboration on WBG-based server and gaming PC power solutions

July 8, 2022

Global megatrends, such as digitization and decarbonisation, require broadband (WBG) devices (SiC / GaN). Due to their unique properties, they enable the highest performance and energy efficiency at the same time. Targeting both of these domains, Infineon Technologies AG in Munich, Germany and the power supply manufacturer Delta Electronics Inc have deepened their collaboration.

The latest examples of their collaboration include Delta’s 1.4 kW server power supply and a 1.6 kW Titanium gaming power platform. The 1.4 kW server power supply utilizes Infineon’s CoolSiC MOSFET technology and Delta’s decades of expertise in power electronics to achieve more than 96% efficiency. Another case for maximum efficiency is the 1.6 kW gaming power platform powered by Infineon’s CoolGaN technology supplemented with EiceDRIVER port driver ICs. The efficiency of this design reaches 96% at a wide range of inputs and multi-outputs and meets the titanium standard in the industrial domain. This is activated by Infineon’s CoolGaN gate-injected transistor (GIT) 600V enhancement-mode high-electron-mobility transistor (e-mode HEMT), adapted in an interleaving totempole power factor correction (PFC) topology.

Both design examples show how Infineon’s broad, performance-driven portfolio of WBG devices, together with Delta’s system innovation potential, can enable new levels of efficiency to meet and exceed modern application requirements, the companies say. By deepening the collaboration, both companies aim for a leading position in WBG-based platforms through cost-effective, robust solutions supported by what is claimed to be the highest supply stability.

“Given our commitment to invest over 8% of our annual revenue in R & D-based innovation, Delta’s power supply solutions for servers and gaming PCs provide the high-quality and high-efficiency components needed to build customized, reliable and energy-efficient infrastructure that satisfies customers’ expectations, ”claims Jimmy Yiin, VP and general manager of Delta’s Power and System Business Group. «Succeeding in such an extremely competitive environment requires collaboration with highly reliable, top-level component suppliers with comprehensive system understanding and offering fully customized solutions for application-specific requirements. Infineon’s inclusive portfolio of WBG products made it possible to achieve industry-leading energy efficiency for many of our customers’ applications, ”he adds.

“Our production scale and technological excellence, combined with a focus on quality and reliability at every step of the value chain, are the key to success factors for our broadband semiconductor business and are well recognized by our customers,” said Johannes Schoiswohl, Business Line Manager, Efficient Power Supply, Insulation and connection to Infineon’s power and sensor systems. “By applying rigorous qualification and reliability testing procedures to our devices, beyond standard JEDEC qualification, we can predict long-term behavior of our WBG devices and ensure field reliability throughout the product life cycle. We are excited about the opportunities our partnership with Delta gives us. in the server and gaming market. ”
