Wise Integration Launches First Digital Controller, WiseWare® 1.1, for GaN Totem Pole PFC with High Switching Frequency Up to 2 MHz

With WiseWare® 1.1, GaN-Based Designs Achieve Compact Size and Peak Efficiency

Hyeres, France – June 26, 2025 – Wise Integration, a pioneer in digital control for gallium nitride (GaN) and GaN IC-based power supplies, today announced the release to production of its first fully digital controller, WiseWare 1.1 (WIW1101) based on the MCU 32 bits. This milestone innovation enables high-frequency operation up to 2 MHz, unlocking new levels of power density, efficiency, and form factor in compact AC-DC power converters.

The product is now available and ready for volume production in customer-validated designs.

“This release marks a strategic milestone for Wise Integration’s roadmap,” said Thierry Bouchet, CEO of Wise Integration. “WiseWare 1.1 represents more than a product—it’s a key pillar in our vision to redefine power electronics through digital control. It strengthens our value proposition in high-density power conversion and reinforces our leadership as GaN technology scales to mass adoption.”

Digitally Driven, GaN Optimized

Unlike legacy analog solutions, WiseWare 1.1 leverages the speed and switching capabilities of GaN (gallium nitride) through a proprietary digital control algorithm in a MCU 32 bits, that enables zero voltage switching (ZVS) across all power transistors. Designed specifically for totem pole power-factor correction (PFC) architectures in critical-construction mode (CrCM), this controller allows engineers to dramatically reduce the size, weight, and thickness of magnetic components while maintaining >98 percent efficiency.

Customer-Proven Performance and Global Momentum

WiseWare 1.1 supports a broad power range from 100 W to 1.5 kW, making it suitable for a wide array of modern applications requiring both compactness and high energy efficiency.

Designed with flexibility in mind, WiseWare 1.1 works seamlessly with standard GaN across the full RDS(on) spectrum (drain-source on-resistance), giving power designers the freedom to choose the optimal transistor for each application—without compromising performance.

Typical applications include:

• High-efficiency AC-DC power converters,
• High-power density designs,
• Power supplies for servers,
• USB power delivery adapters for laptops and notebooks, and
• Switch-mode power supplies for monitors and displays.

The WiseWare 1.1 platform has already demonstrated robust market validation, with multiple customer design-ins and live demos at PCIM Europe, one of the industry’s most prominent power- electronics exhibitions. These demonstrations showcased 300W totem pole PFC converter boards using WiseWare 1.1 and WiseGan® WI71060A transistors (RDS(on)=60mohms), operating from 90–264 VAC input to a 400 VDC output. At the same time, technical collaborations are progressing in Asia, reinforcing the company’s global reach.
