Efficiency approaching 96%, light-load performance, and cost-efficient BOM enabled by Eggtronic’s EPIC™ digital power architecture and Renesas HV GaN technology

The demand for compact, cost effective, highly efficient USB-C power adapters continues to grow rapidly.”

— Igor Spinella, Founder and CEO of Eggtronic

MODENA, EMILIA-ROMAGNA, ITALY, September 14, 2026 /EINPresswire.com/ — Eggtronic, a leader in energy-efficient power conversion technologies, today announced the availability of a 140W USB-C Power Delivery AC/DC reference platform for next-generation premium laptops and high-performance devices. This reference design is developed based on Renesas’ high-voltage GaN transistors.

The new platform combines Eggtronic’s EPIC™ combo controller with Renesas’ high-voltage GaN device, the TP70H150G4LSG (700V, 150 mΩ RDS(on)), delivering an unprecedented combination of extreme efficiency, outstanding cost-effectiveness, and simplified system architecture.

Unlike conventional high-power USB-C adapters that rely on costly LLC, Asymmetrical Half-Bridge (AHB), or Active Clamp Flyback (ACF) topologies, the new reference design achieves efficiencies approaching 96% while maintaining the bill of materials cost of a traditional QR flyback converter.

The platform also delivers excellent efficiency across the entire operating range, including 94.5% efficiency at 90 VAC input and outstanding light-load performance, enabling compliance with the latest DOE Level VII energy efficiency requirements.

At the heart of the solution is Eggtronic’s EPIC™ combo controller, which integrates every major control function into a single device, including:

• Totem Pole Power Factor Correction (PFC)
• Isolated primary-side regulation
• Synchronous rectification
• Proprietary ultra-low-latency isolated communication
• USB Power Delivery protocol management

The platform’s Totem Pole PFC overcomes two of the most common limitations of conventional implementations—EMI performance and light-load efficiency—while maintaining industry-leading conversion efficiency.

The PFC stage feeds Eggtronic’s proprietary QuarEgg™ regenerative flyback architecture, which utilizes a single primary-side switch to achieve higher efficiency and lower system cost than LLC, AHB, and ACF converters while maintaining the simplicity and economics of a QR flyback design.

“The demand for compact, cost effective, highly efficient USB-C power adapters continues to grow rapidly,” said Igor Spinella, Founder and CEO of Eggtronic. “By combining Renesas’ outstanding GaN technology with our EPIC™ combo-controller, we have created a platform that significantly raises the bar for both efficiency and cost-effectiveness. We believe this reference design provides OEMs with a compelling path toward the next generation of premium power adapters.”

Rohan Samsi, Vice President, GaN Business Division at Renesas, added: “Renesas is committed to enabling the next generation of highly-efficient and cost-effective power solutions through our advanced GaN technology. The reference platform is a direct result of our collaboration with Eggtronic, which brings together complementary expertise in power conversion and digital control. It gives customers a strong foundation for developing compact, high-performance power systems such as USB-C charging at a competitive cost.”

The 140W USB-C Power Delivery reference board is available now and is intended to accelerate the development of high-performance notebook adapters and other USB-C powered devices.
