Wise Integration launches WiseWare 1.1 -- first digital controller

Wise Integration, a pioneer in digital control for gallium nitride (GaN) and GaN IC-based power supplies, released to production 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.
