Top 10 GaN Power Supply Trends OEMs Need to Know in 2026 and Beyond
QUICK LINKS
Why GaN Is Becoming a Strategic Priority for OEM Power Design
GaN is no longer an emerging technology. It is now a strategic decision point for OEMs designing next-generation products. As devices become more powerful and more compact, traditional silicon-based power supplies are increasingly unable to meet the combined demands of efficiency, thermal control, and form factor.
The shift is being driven by real engineering constraints. High-performance devices need more power, but users expect smaller, lighter solutions. GaN addresses this gap by enabling higher switching efficiency and reduced heat generation, allowing designers to push power density without expanding size.
This transition aligns with global design and compliance expectations. Organizations such as the International Electrotechnical Commission (IEC) (https://www.iec.ch) continue to emphasize efficiency, safety, and thermal stability as core requirements for modern power systems. GaN supports all three, making it a natural evolution in power design.
Phihong’s GaN product direction reflects this shift. Across its adapter portfolio, GaN is positioned as a foundation for compact, high-performance power solutions that meet both engineering and market demands.

Top 10 GaN Power Supply Trends OEMs Need to Know in 2026 and Beyond
1. GaN Is Becoming the Standard for High-Density Power Design
GaN is rapidly replacing silicon in high-density applications because it allows more power to be delivered in less space. This trend is especially visible in the 65W to 330W range, where size and efficiency are critical.
OEMs are increasingly designing products around GaN from the beginning rather than treating it as an upgrade. This shift reflects the growing importance of power density in modern device design.
2. USB-C Power Delivery Will Dominate Power Interfaces
USB-C PD is becoming the universal standard for power delivery across devices. GaN adapters are well-suited for this transition because they support high power levels in compact formats.
OEMs are moving away from proprietary connectors and toward standardized interfaces. This simplifies product ecosystems and improves user experience.
3. Thermal Efficiency Will Drive Design Decisions
As devices become more compact, thermal performance becomes more important. GaN’s ability to reduce heat generation makes it a key enabler of modern designs.
OEMs are prioritizing thermal efficiency to improve reliability and reduce the need for complex cooling systems.
4. Multi-Device Charging Will Become More Common
Users increasingly expect a single adapter to power multiple devices. GaN supports this by enabling higher power output and dynamic power distribution.
This trend is driving the development of multi-port adapters that can handle multiple loads simultaneously.
5. Higher Wattage GaN Adapters Will Expand Rapidly
GaN is enabling higher wattage adapters without the traditional size increase. This is leading to rapid growth in the 100W+ and 300W+ categories.
OEMs are adopting these solutions to support high-performance devices while maintaining portability.
6. Integration with Smart Power Management Systems Will Increase
GaN adapters are increasingly being integrated with smart power management systems. This allows for real-time monitoring and optimization of power delivery.
OEMs are using these capabilities to improve efficiency and extend device lifespan.
7. Global Power Compatibility Will Become a Standard Requirement
As products are sold globally, power supplies must support a wide range of input voltages. GaN adapters are well-suited for this because of their efficiency and flexibility.
OEMs are prioritizing global compatibility to simplify logistics and reduce costs.
8. Sustainability and Energy Efficiency Will Gain Importance
Energy efficiency is becoming a key factor in product design. GaN supports sustainability goals by reducing energy waste.
OEMs are adopting GaN to meet regulatory requirements and improve environmental impact.
9. Compact Form Factors Will Continue to Shrink
As GaN technology advances, adapter sizes will continue to decrease. This trend supports the development of smaller and lighter devices.
OEMs are leveraging this to improve product design and user experience.
10. GaN Will Enable New Categories of Portable Devices
The combination of high power and compact size is enabling new types of portable devices. This includes advanced medical equipment, industrial tools, and high-performance consumer electronics.
OEMs are exploring these opportunities to create innovative products that were not previously possible.
GaN is not just a technology trend. It is a fundamental shift in how power supplies are designed and integrated into modern devices. OEMs that understand and adopt these trends will be better positioned for future success.
