Alpha and Omega Semiconductor (AOS) has introduced a new family of digital multiphase controllers designed for Intel’s next-generation Panther Lake and Wildcat Lake mobile processor platforms.
The company announced the launch of the AOZ71049QI, AOZ71149QI, and AOZ71146QI controllers, developed specifically for Intel IMVP9.3 Vcore power delivery requirements. The controllers are designed to work alongside AOS’s DrMOS and Smart Power Stage (SPS) technologies to provide a complete power management solution for upcoming laptops and notebooks.
The launch comes as semiconductor companies focus on improving power efficiency, thermal performance, and battery life in AI-enabled mobile computing devices.
According to AOS, the new controller family uses the company’s proprietary Advanced Transient Modulation (A2TM) technology. The system combines digital tuning flexibility with analog efficiency through variable-frequency hysteretic peak-current mode control and advanced phase-current sensing.
The company said the approach enables faster transient response and improved current balancing across both transient and DC loads.
AOS also highlighted low quiescent power consumption as a key feature of the platform. Lower idle power consumption is increasingly important for extending battery life in thin-and-light notebooks and AI PCs.
Wayne Lee, Power IC Product Marketing Director at AOS, said balancing performance and power consumption remains one of the major challenges in mobile SoC power delivery.
He said the AOZ71049 series was developed to meet Intel’s latest power requirements while reducing quiescent power consumption. According to the company, the solution can extend laptop battery life by 30 to 60 minutes compared to competing products.
The controllers support flexible phase configurations of up to 4+2+1+2 outputs for processor core, graphics, auxiliary, and LPCORE domains. The company said the devices also include autonomous phase shedding and automatic discontinuous conduction mode (DCM) features to optimize power efficiency.
Additional features include support for industry-standard DrMOS and driver-plus-MOSFET power stages, along with built-in acoustic noise suppression technologies designed to maintain silent operation under varying workloads.
To simplify product development, AOS said system configurations can be programmed directly into the controllers through Multi-Time Programmable Memory using a graphical user interface. This removes the need for manual solder rework during tuning and helps reduce overall bill-of-materials costs.
The company said the platform achieves peak performance when paired with the AOZ52986QI Smart Power Stage.
The AOZ52986QI features a compact 3×4 QFN package and symmetrical pinout aimed at simplifying PCB layout and reducing parasitic inductance. The device supports a 2.7V to 22V supply range and includes a 30V high-side MOSFET designed to improve system reliability.
AOS said the Smart Power Stage supports 45A continuous output current and peak current up to 80A. The device also integrates current and temperature monitoring capabilities for precision power management.
The products are now available in production quantities. The AOZ71049QI, AOZ71146QI, and AOZ71149QI controllers carry lead times of 12 to 16 weeks. Pricing in 1,000-unit quantities ranges from $2.66 to $2.75.
The AOZ52986QI Smart Power Stage is immediately available, with lead times of 16 to 18 weeks and pricing starting at $1.50 in 1,000-piece quantities.
