Munich, Germany – Infineon Technologies AG provides CoolGaN™ power transistors to Universal Microelectronics Co., Ltd. (UMEC) for the company’s new 250 W adapter for networking Power over Ethernet (PoE) applications. Infineon´s CoolGaN transistors enable reliable, high-performance solutions and help UMEC develop safer and energy-efficient technology to address modern power system challenges. These solutions are ideal for power electronics across various industries, including telecommunications, industrial electronics, medical technology, and consumer electronics.
GaN-based power devices provide higher efficiency, reducing heat generation and energy consumption. They can operate at higher frequencies and power densities, enabling more compact designs, maximizing rack space utilization, and improving cooling in AI data centers, for example. Furthermore, reducing system size allows for more hardware content and improved air flow, which results in less wasted heat and ultimately decreases operational costs and the overall carbon footprint.
“We are excited to see our CoolGaN technology powering UMEC’s new 250 W adapter for networking applications. This collaboration demonstrates the potential of GaN to revolutionize the data center industry, enabling smaller, more efficient, and reliable power solutions,” says Johannes Schoiswohl, Head of GaN Business Line at Infineon.
“Partnering with Infineon and utilizing their CoolGaN power transistors in our new 250 W adapter has allowed us to create a product that delivers exceptional efficiency and reliability,” says Richard Lin, Power Supply Product Manager at Universal Microelectronics. “This innovation aligns with our commitment to developing cutting-edge electronic solutions that meet the evolving demands of the networking industry.”
UMEC’s 250 W adapter offers excellent efficiency of 95 percent, a power density increase of around 39 percent. The CoolGaN transistors reduce power losses, enable switching at frequencies above 200 kHz, and improve thermal behavior, which is critical for compact and high-density power supplies. These are critical performance improvements in the global virtual networking market, which is expected to grow from $48.6 billion in 2024 to approximately $200 billion by 2030, at a CAGR of 26.5 percent[1].
Infineon’s gallium nitride power transistors are driving digitalization and decarbonization, while enabling high-frequency operation, increasing efficiency and reducing system size in a wide range of applications. They are available in voltage classes from 60 V to 700 V and in a broad variety of packages.
