Renesas Electronics Corp, a renowned semiconductor manufacturer, has announced a new collaboration with Intel to enhance battery efficiency in the next generation of laptops equipped with Intel Core Ultra 200V series processors. Leveraging this partnership, Renesas has developed a comprehensive power management solution designed specifically for these cutting-edge laptops, which are often tasked with running power-intensive AI applications.
This tailored power management solution is built around a new Power Management Integrated Circuit (PMIC) along with a pre-regulator and battery charger, forming an all-encompassing package. The design focuses on enabling low-power, high-performance computing in portable devices, meeting the unique power consumption needs of modern laptops.
Key to this solution is the RAA225019 configurable PMIC, designed explicitly for the new Intel Core Ultra 200V series, internally referred to as Lunar Lake applications. This PMIC integrates power MOSFETs and current sensing circuitry, allowing it to maintain a compact form factor without sacrificing efficiency. Its high switching frequency capability plays a crucial role in supporting smaller device designs, essential for contemporary laptops.
Complementing the PMIC is the RAA489301 pre-regulator. This component is a high-efficiency, three-level buck controller that offers optimal voltage management for the PMIC, thus enhancing power density and thermal performance. Its architecture marks a departure from traditional two-level buck designs, delivering a wide input and output range for improved efficiency and thermal regulation, particularly in compact, high-power applications.
The third element of the solution, the ISL9241 battery charger, adds versatility with its digitally-configurable buck-boost capabilities and an SMBus interface for USB power delivery. This charger supports both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB/Bypass) modes, with the flexibility to switch modes via firmware. The bypass mode facilitates direct power delivery from an adapter to the system, providing an additional efficiency boost.
The introduction of these technologies underscores the dedication of both Renesas and Intel to enhance mobile computing efficiency, particularly for machines running complex AI algorithms. As these three devices—the RAA225019 PMIC, RAA489301 pre-regulator, and ISL9241 battery charger—are now available from Renesas, they represent significant progress in the development of power systems that can deliver both performance and sustainability for future laptop generations.
