A Power Shift That's Just Beginning

OmniOn Power™ Introduces New Osprey-Series Non-Isolated Bus Converters for AI Server Applications

Boasting peak efficiencies of up to 97.6%, the new Osprey bus converters feature a 40-60VDC input range and can transform 48V unregulated DC rack voltages into the regulated 12VDC output power required by high-performance GPUs with minimal power loss.


The converters incorporate digital control, synchronous rectification technology, a regulated control topology, and innovative packaging techniques to achieve high efficiencies and provide low output ripple and noise.



The modules offer a wide operating temperature range of -40°C to 85°C and incorporate a heat plate that allows for external heat sinks to be attached or for contact with a cold wall.

Attopsemi Expands its Proven I-fuse® OTP Portfolio on X-FAB’s 180nm Platform

The I-fuse S3® OTP (whereby S3 means “super-small and scalable”) is an innovation in peripheral design that complements the I-fuse® cell technology. By employing a novel array architecture, it achieves a compact form factor and scalability, closely following Moore’s Law for small to medium-sized OTP applications.


This innovation is incorporated into X-FAB’s XH018, a powerful modular sensor and high-voltage EPI technology, supporting an extended temperature range from -40°C to 175°C. It features a modular 1.8V/3.3V ultra-low-noise process designed for automotive-grade, industrial, and medical applications.

Infineon CoolGaN™ Power Transistors Enable SounDigital to Reach Higher Fidelity in Smaller Amplifier Systems

With their low on-resistance, the transistors are ideal for demanding high-current applications, enabling significant improvements in both sound quality and efficiency of SounDigital’s amplifier.


The GaN-based amplifier also delivers high performance while reducing power dissipation by 75 W, allowing for a 50 percent smaller heat sink. Additionally, the overall system size has been reduced by 40 percent without compromising performance.


The audio quality has been further improved by the CoolGaN transistors, with total harmonic distortion (THD) reduced by 70 percent, enabling a more precise and detailed sound experience. At the same time, the idle current has been reduced by 40 percent, significantly improving energy efficiency.

Why GaN? Why Now?

Silicon’s been great, but it’s got limits—especially when it comes to switching speed, efficiency, and power density. GaN, on the other hand, is a wide-bandgap semiconductor, meaning it can handle higher voltages, switch way faster, and waste less energy. Think of it like upgrading from an old steam locomotive to a high-speed maglev train.


But here’s the thing: GaN is powerful, but it’s not always easy to work with. That’s where Integrated CoolGaN™ comes in—it makes GaN simpler, more reliable, and ready for real-world applications.


What Makes CoolGanSo "Cool"?


Everything You Need, All in One

Traditional GaN transistors need external gate drivers and complex circuitry to function. Integrated CoolGaN™ takes care of that, bundling in optimized gate driving, protection features, and better thermal management. Less hassle, more power, basically.

Super Fast Switching

GaN can switch up to 10 times faster than silicon MOSFETs. That means higher efficiency, smaller components, and way less heat—huge wins for data centers, EV chargers, and compact power supplies.


Efficiency Without the Annoyance

You don’t have to be a power electronics guru to design with GaN anymore. Integrated CoolGaN™ makes high-performance power conversion almost plug-and-play—or at least as close as it’s ever been.


Where You’ll See CoolGaN™ in Action


  • Ultra-Fast Chargers & Adapters – Say goodbye to bulky chargers and overheating power bricks. Be gone!
  • Data Centers – Lower energy bills, less heat, and a smaller carbon footprint? Yes, please.
  • EV Onboard Chargers – Faster, more efficient charging for electric vehicles—because who likes waiting? Not me.
  • Renewable Energy – Solar inverters and grid applications get a serious efficiency boost.


The Future is GaN-tastic

GaN isn’t just an upgrade—it’s a whole new way to think about power electronics. And with Integrated CoolGaN™, the barriers to entry are disappearing fast. The industry is shifting toward smaller, faster, and more efficient solutions, and GaN is at the center of it all. So whether you’re an engineer, an innovator, or just someone who likes their devices running cooler and charging faster, one thing’s for sure: the future of power is here, and it’s looking pretty electrifying.


Where do you see the biggest opportunity for GaN to make an impact—EVs, data centers, or something entirely new? Send me your thoughts.
