Wise Integration has released its first fully digital controller, WiseWare 1.1 (WIW1101), based on a 32-bit MCU. 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.
“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 analogue solutions, the device utilises the speed and switching capabilities of GaN through a proprietary digital control algorithm in a 32-bit MCU, which enables ZVS across all power transistors. Designed specifically for totem pole PFC architectures in critical-construction mode (CrCM), this controller allows engineers to significantly reduce the size, weight, and thickness of magnetic components while maintaining an efficiency of greater than 98%.
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, the device works seamlessly with standard GaN across the full RDS(on) spectrum (drain-source on-resistance), providing power designers with the freedom to select the optimal transistor for each application without compromising performance.
Typical applications include:
