HONG KONG – November 10, 2025 – Gallium Nitride (GaN) technology continues to revolutionize the power electronics landscape, offering unprecedented levels of efficiency, power density, and switching speed. As we approach 2026, the adoption of GaN is set to accelerate across a broader range of applications. LiTong Group, as a leading distributor of Power Integrations' GaN-based solutions, provides an outlook on the key trends shaping the GaN market.
1. Continued Dominance in Fast Chargers
GaN has already established itself as the technology of choice for USB-PD fast chargers, enabling smaller, lighter, and more efficient power adapters for smartphones, laptops, and tablets. This trend will continue, with GaN penetrating even higher power segments and becoming standard in multi-port chargers. The integration of GaN with advanced control ICs, such as Power Integrations' InnoSwitch™ with PowiGaN™, will further drive this adoption.

2. Expansion into Automotive Applications
The automotive sector is increasingly turning to GaN for electric vehicle (EV) applications, particularly in on-board chargers (OBCs), DC-DC converters, and even traction inverters. The high-temperature capability and superior switching performance of GaN are critical for improving EV range, reducing charging times, and enabling more compact power systems. Expect to see more AEC-Q100 qualified GaN solutions entering the market.
3. Growth in Data Centers and Enterprise Power
With the ever-increasing demand for data processing, data centers are under pressure to improve energy efficiency. GaN-based power supplies offer significant advantages in server power supplies, uninterruptible power supplies (UPS), and other enterprise power applications by reducing energy losses and enabling higher power density, which translates to lower operational costs and a smaller physical footprint.
4. Industrial and Renewable Energy Adoption
Beyond consumer and automotive, GaN is making inroads into industrial power supplies, solar inverters, and energy storage systems. Its ability to handle high voltages and currents with high efficiency makes it an attractive alternative to traditional silicon-based devices in these demanding environments. The robustness and reliability of GaN will be key drivers for its adoption in these sectors.
5. Increased Integration and Ease of Use
To accelerate adoption, semiconductor manufacturers like Power Integrations are focusing on higher levels of integration, combining GaN switches with control ICs and protection features into single packages. This simplifies design, reduces external component count, and makes GaN technology more accessible to a wider range of engineers, even those without extensive experience in wide-bandgap semiconductors.
Conclusion
The outlook for GaN technology in 2026 is exceptionally strong, with continued growth in established markets and significant expansion into new, high-value applications. LiTong Group is committed to supporting this transition by providing access to Power Integrations' leading GaN solutions and expert technical guidance. As the technology matures and becomes more integrated, GaN will undoubtedly play a pivotal role in shaping the future of power electronics.
