Wise Integration Digital Controller Enables Switching Frequencies Up to 2MHz
Wise Integration has 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 2MHz, 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.”
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 32-bit MCU, which 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% efficiency.
WiseWare 1.1 supports a broad power range from 100W to 1.5kW, 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 90–264VAC input to a 400VDC output. At the same time, technical collaborations are progressing in Asia, reinforcing the company’s global reach.
