Transphorm Inc. confirmed that its GaN FETs are used in CORSAIR’s new AX1600i Power Supply Unit (PSU). CORSAIR supplies the gaming community with high-performance products used in custom PCs. The company’s latest product establishes a new class of AC-to-DC PSUs, as it is the first to use GaN and achieves 99% efficiency. Transphorm’s GaN increases the PSU’s power output by 6.5% in an 11% smaller package at the same temperature. The AX1600i uses Transphorm’s TPH3205WS 650V FETs in a bridgeless totem-pole power factor correction (PFC)—the topology that complements GaN’s performance and efficiency potential. With an increase of 6% within this topology, CORSAIR’s PSU efficiency now earns a better-than an 80 PLUS® Titanium rating. [Previous CORSAIR power supplies used Silicon (Si) superjunction (SJ) MOSFETs in a 2-phased interleaved PFC, reaching 93% efficiency.] Transphorm’s commitment to high quality and reliability extends beyond the technology. Gallium Nitride devices are higher frequency, sometimes requiring different design techniques than previously used with Si. The company’s GaN experts collaborate regularly with customers to provide guidance and to identify areas of opportunity for future platform innovation and customer design resources. Regarding the AX1600i project, Transphorm supported CORSAIR during both the prototyping and the design validation testing phases. CORSAIR tapped Transphorm’s teams on the ground in Shenzhen, China, and California, U.S.
