Renesas collaborates with Intel on power management

Renesas Electronics Corporation has collaborated with Intel to develop a power management product that delivers best-in-class battery efficiency for laptops based on the new Intel® Core™ Ultra 200V series.

Renesas developed an innovative customized power management IC (PMIC) that covers the entire power management needs for this newest generation of Intel processors. This advanced and highly integrated PMIC, combined with a pre-regulator and a battery charger, offers a complete solution for PCs leveraging the new Intel processor. The three new devices work together to provide a purpose-built power system targeted at client laptops, particularly those running AI applications that tend to consume a lot of power.

The new power management devices include the RAA225019 PMIC, the RAA489301 high-efficiency pre-regulator, and the ISL9241 battery charger. These devices have a feature set optimized for low-power mobile computing applications. Renesas products are backed by tested reference designs and strong application support.

The RAA225019 PMIC is highly configurable for Lunar Lake applications and features fully integrated power MOSFETs and current sensing circuitry. It supports high switching frequencies, making it well suited for small form factor applications without compromising efficiency.

The RAA489301 pre-regulator is a 3-level buck converter designed to provide an optimized voltage range for the RAA225019 PMIC. Its innovative architecture enhances thermal performance compared to traditional 2-level buck designs, and it supports a wide input and output voltage range. This allows for superior efficiency in compact, high-power-density applications, making it an ideal choice for demanding power management requirements.

“With the launch of the newest Intel Core Ultra processors, we are committed to delivering the best battery life experience possible for our customers,” said Josh Newman, Vice President, Client Computing Group and General Manager, Product and Platform Marketing at Intel.   “Our mutual commitment with Intel to AI-powered mobile benefits every user with leading-edge technology,” said Tom Truman, Vice President and General Manager, Performance Computing Power at Renesas. “This offering demonstrates the depth and breadth of our power technology and highlights our ability to stay ahead of emerging market trends.”

The RAA225019 PMIC, the RAA489301 high efficiency pre-regulator, and the ISL9241 battery charger are available today.
