Infineon and Delta strengthen collaboration on WBG-based server and gaming PC power solutions
Global megatrends, such as digitalization, and decarbonization, call for wide-bandgap (WBG) devices (SiC/GaN). Due to their unique characteristics, they enable the highest performance and energy efficiency at the same time. Targeting both of these domains, Infineon Technologies AG of Munich, Germany and power supply maker Delta Electronics Inc have deepened their collaboration.
The latest examples of their cooperation include Delta’s 1.4kW server power supply and a 1.6kW Titanium gaming power platform. The 1.4kW server power supply leverages Infineon’s CoolSiC MOSFET technology and Delta’s multi-decade core competence in power electronics to achieve beyond 96% efficiency. Another case for highest efficiency is the 1.6kW gaming power platform powered by Infineon’s CoolGaN technology complemented with EiceDRIVER gate driver ICs. The efficiency of this design reaches 96% at wide-range input and multi-output and meets the Titanium standard in the industrial domain. This is enabled by Infineon’s CoolGaN gate-injected transistor (GIT) 600V enhancement-mode high-electron-mobility transistor (e-mode HEMT), adapted in an interleaving totem-pole power factor correction (PFC) topology.

Both design examples demonstrate how Infineon’s broad, performance-driven portfolio of WBG devices, together with Delta’s system innovation potential, can enable new efficiency levels to meet and exceed modern application requirements, the firms say. By deepening their collaboration, both companies target a leading position in WBG-based platforms through cost-effective, robust solutions backed up by what is claimed to be the highest supply stability.
“Given our commitment to investing over 8% of our annual revenues 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 which satisfies our customers’ expectations,” claims Jimmy Yiin, VP & general manager of Delta’s Power and System Business Group. “Being successful in such an extremely competitive environment requires collaborating with highly trustworthy, top-tier component suppliers with extensive 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 customer’s applications,” he adds.
“Our manufacturing scale and technology excellence, combined with a focus on quality and reliability at each step of the value chain, are the key to success factors for our wide-bandgap semiconductor business and are well recognized by our customers,” reckons Johannes Schoiswohl, business line head, Efficient Power Supplies, Isolation & Connectivity of Infineon’s Power & Sensor Systems Division. “By applying rigorous qualification and reliability test procedures to our devices, above and beyond standard JEDEC qualification, we can predict the long-term behavior of our WBG devices and ensure reliability in the field over the entire product lifecycle. We are excited about the opportunities our collaboration with Delta holds for us in the server and gaming market.”
