NEWS 5 Power Electronics Europe Issue 3 2025 Power Electronics Europe Navitas Semiconductor, an industry leader in next-generation GaNFast gallium nitride (GaN) and GeneSiC silicon carbide (SiC) power semiconductors, has announced that Xiaomi’s next-generation 90W GaN charger will be powered by Navitas’ GaNSense Control ICs. Reportedly the world’s smallest 90 W charger, the company says this ultra-compact, high-power-density form-factor measures just 34 45 34 mm and weighs only 65 grams—approximately half the size and a third the weight of typical GaN chargers. The charger integrates Navitas’ NV9580 GaNSense Control power IC on the primary side and the NV9701 synchronous rectification controller IC on the secondary side. The GaNSense Control family combines 4th generation GaN power with high-frequency control functionality. It provides all the benefits of a monolithically integrated GaN power FET and GaN drive, plus a controller and protection features in a single surface-mount package for high-density, highefficiency chargers, adapters, and auxiliary power designs. GaNSense Control ICs are said to deliver the highest-frequency operation to minimise system size and weight. Integrated features such as lossless current sensing, high-voltage start-up, and elimination of VDD inductor reduce component count and increase system efficiency. With transient voltage breakdown up to 800 V and no PCB hotspots, Navitas’ GaNSense Control ICs can deliver best-inclass efficiency in the smallest form factor. “The launch of Xiaomi’s 90W GaN charger marks a new milestone in our long-standing collaboration with Xiaomi,” said Charles Zha, SVP and APAC GM of Navitas. “Combining the innovation of GaNSense Control ICs and Xiaomi’s leading system expertise, we have delivered a new benchmark for ultra-portable fast-chargers. Navitas will continue our partnership with Xiaomi to continue future innovations with our GaN technology.” https://navitassemi.com/ requirements. Adherence safeguards sensitive electronics from extreme voltage variations inherent in military ground vehicles, while saving time, effort and cost in product design, testing and qualification. Additionally, the 3U VPX Power Supply incorporates AirBorn’s advanced internal filtering to meet stringent EMI/RF requirements. Integrated EMI suppression capability is designed to meet MIL-STD-461-conducted EMI emission requirements without external filtering. A testament to AirBorn’s proven power engineering expertise, this unique functionality mitigates interference at the source to reduce signal degradation, lower crosstalk and enhance data transmission rates. “For customers building highly compact 3U VPX systems, the opportunity to leverage an ‘all-in-one’ power supply that handles power conversion and EMI filtering on a single printed circuit board is very compelling,” said Scott Poole, director, Design and Development Engineering at AirBorn. “We apply extensive engineering expertise and special processes to develop highly efficient power engines capable of achieving low noise switching, clean conducted emissions, ultra-clean output voltages and versatility in parallel VPX cards.” Meeting Bigger Power Demands in Smaller Footprints The AirBorn 3U VPX Power Supply is well positioned to deliver continuous operation in rigorous conditions common for military ground vehicles, which can create voltage spikes and surges. When space is at a premium, the new 3U VPX model can safeguard essential onboard systems and applications, such as Low Earth Orbit (LEO) satellites, unmanned aerial vehicles (UAVs), industrial automation, robotics and AI-driven distributed systems. This transfer of military-grade ruggedization and reliability to other applications and industries will be universally appealing to engineers and systems integrators committed to ensuring flawless power delivery and seamless systems integration of sensitive electronics. www.molex.com.
