Murata adopts EcoGaN for AI server power supplies
Rohm has announced that the EcoGaN series of 650V GaN HEMTs in the TOLL package has been adopted for AI server power supplies by Murata Power Solutions for its 5.5kW AI server power supply unit.
Mass production of the power supply unit is set to begin in 2025.
Joe Liu, technical fellow, Murata Power Solutions said: “We are pleased to have successfully designed AI server power supply units featuring higher efficiency and power density by incorporating Rohm’s GaN HEMTs. The high-speed switching capability, low parasitic capacitance, and zero reverse recovery characteristics of GaN HEMTs help minimise switching losses. This allows for higher operating frequencies in switching converters, reducing the size of magnetic components.”
Yuhei Yamaguchi, general manager, power stage product development at Rohm said:“The GaN HEMTs used in this application provide industry-leading switching performance in a high heat dissipation TOLL package, enhancing power density and efficiency in Murata Power Solutions’ power supply units.”
Murata Power Solutions’ series of “1U Front End” AC-DC power supplies includes the D1U T-W-3200-12-HB4C (12V output) and D1U T-W-3200-54-HB4C (54V output) 3.2kW power supplies in the high power density short version M-CRPS package, as well as the 5.5kW D1U67T-W-5500-50-HB4C designed for AI servers.
These front-end power supplies deliver high conversion efficiency that meets the stringent requirements of 80+ Titanium and Open Compute products while supporting N+m redundant operation for system reliability, making them ideal for powering the latest GPU servers.
In addition to providing reliable, efficient power for servers, workstations, and storage/communication systems, the low profile 1U design of these units helps to minimise system footprint.
