New Digital Multiphase Controllers and Smart Power Stages deliver industry-leading low quiescent power, extending mobile battery life by up to an hour

The Hybrid Advantage: Digital Tuning, Analog Efficiency

The AOZ71049QI series utilizes the proprietary AOS Advanced Transient Modulation (A²TM). This technology bridges the gap between digital flexibility and analog efficiency, combining variable-frequency hysteretic peak-current mode control with advanced phase-current sensing. This results in ultra-fast transient response and optimal current balance across both transient and DC loads. A key differentiator is the exceptionally low quiescent power consumption across all Intel IMVP 9.3 power states. By reducing power waste, the solution maximizes battery longevity in next-generation laptops and notebooks.

Simplified Design and Superior Thermals

To streamline the development cycle, configurations can be programmed directly into the controller’s Multi-Time Programmable Memory (MTP) via a user-friendly GUI. This eliminates the need for manual solder rework during the tuning phase and reduces the overall bill of materials (BOM).

The solution reaches peak performance when paired with the AOZ52986QI Smart Power Stage (SPS). Featuring a compact 3×4 QFN package and a symmetrical pinout, the AOZ52986QI simplifies PCB layout while reducing parasitic inductance by 5%.

“The biggest hurdle for SoC power in mobile applications is balancing performance with power consumption,” said Wayne Lee, Power IC Product Marketing Director at AOS. “Our AOZ71049 series provides a novel control scheme that meets Intel’s most stringent requirements while delivering the lowest quiescent power in the industry. For the end user, this translates to 30 to 60 minutes of additional battery life compared to competing solutions.”
