With WiseWare 1.1, GaN-Primarily based Designs Obtain Compact Measurement and Peak Effectivity
Smart Integration, a pioneer in digital management for gallium nitride (GaN) and GaN IC-based energy provides, introduced the discharge to manufacturing of its first totally digital controller, WiseWare 1.1 (WIW1101) based mostly on the MCU 32 bits. This milestone innovation permits high-frequency operation as much as 2 MHz, unlocking new ranges of energy density, effectivity, and kind think about compact AC-DC energy converters. The product is now prepared for quantity manufacturing in customer-validated designs.
“This launch marks a strategic milestone for Smart Integration’s roadmap,” mentioned Thierry Bouchet, CEO of Smart Integration. “WiseWare 1.1 represents greater than a product—it’s a key pillar in our imaginative and prescient to redefine energy electronics by way of digital management. It strengthens our worth proposition in high-density energy conversion and reinforces our management as GaN know-how scales to mass adoption.”
Digitally Pushed, GaN Optimized
Not like legacy analog options, WiseWare 1.1 leverages the pace and switching capabilities of GaN (gallium nitride) by way of a proprietary digital management algorithm in a MCU 32 bits, that permits zero voltage switching (ZVS) throughout all energy transistors. Designed particularly for totem pole power-factor correction (PFC) architectures in critical-construction mode (CrCM), this controller permits engineers to dramatically cut back the dimensions, weight, and thickness of magnetic elements whereas sustaining >98 % effectivity.
Buyer-Confirmed Efficiency and World Momentum
WiseWare 1.1 helps a broad energy vary from 100 W to 1.5 kW, making it appropriate for a wide selection of recent purposes requiring each compactness and excessive power effectivity.
Designed with flexibility in thoughts, WiseWare 1.1 works seamlessly with commonplace GaN throughout the complete RDS(on) spectrum (drain-source on-resistance), giving energy designers the liberty to decide on the optimum transistor for every software—with out compromising efficiency.
Typical purposes embrace:
- Excessive-efficiency AC-DC energy converters,
- Excessive-power density designs,
- Energy provides for servers,
- USB energy supply adapters for laptops and notebooks, and
- Change-mode energy provides for screens and shows.
The WiseWare 1.1 platform has already demonstrated strong market validation, with a number of buyer design-ins and stay demos at PCIM Europe, one of many business’s most distinguished power- electronics exhibitions. These demonstrations showcased 300W totem pole PFC converter boards utilizing WiseWare 1.1 and WiseGan WI71060A transistors (RDS(on)=60mohms), working from 90–264 VAC enter to a 400 VDC output. On the similar time, technical collaborations are progressing in Asia, reinforcing the corporate’s international attain.
