Infineon CoolGaN technology boosts power performance in network PoE applications
Infineon provides CoolGaN power transistors to Universal Microelectronics 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, maximising rack space utilisation, and improving cooling in AI data centres, 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.
UMEC’s 250 W adapter offers 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 behaviour, 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 available in voltage classes from 60 V to 700 V and in a broad variety of packages.
