Renesas Electronics recently announced a collaboration with Intel to develop a power management solution to improve the battery efficiency of notebook PCs based on the new Intel Core Ultra 200V series processors.
Renesas and Intel have worked closely together to develop an innovative custom power management IC (PMIC) designed to meet the comprehensive power management needs of the latest Intel processors. Integrated power management is an electronic device used to control and regulate the voltage, current, and power of a power supply. It is responsible for the conversion, distribution, detection and other power management of electrical energy in the electronic equipment system, and is mainly responsible for identifying the power supply amplitude of the CPU and generating the corresponding short moment wave to promote the power output of the post-stage circuit. Power management integrated circuits have been widely used in many types of products and perform a range of different functions, including intelligent motor control, power protection circuits, and DC-DC converter/regulator applications. With the popularity of mobile devices and IoT devices, the market demand for power management integrated circuits is growing. Especially in the fields of wearable devices, mobile devices, and sensors, the application prospects of power management integrated circuits are very broad.
The state-of-the-art and highly integrated PMIC, combined with a pre-regulator and battery charger, provides a complete power solution for PCs with new processors. The synergy of these three new devices is particularly suitable for laptops that run AI applications and require a lot of power, ensuring a dedicated power solution for customers.
The new devices include RAA225019 PMICs, RAA489301 high-efficiency pre-regulators, and ISL9241 battery chargers, all optimized for low-power mobile computing applications. Behind Renesas' solutions are proven reference designs and robust application support.

Designed for Lunar Lake applications, RAA225019 PMICs are highly configurable and integrate power MOSFETs and current sense circuitry to support high switching frequencies, making them ideal for small form factor applications without sacrificing efficiency.
The RAA489301 pre-regulator is a three-stage buck converter designed to provide an optimized voltage range for RAA225019 PMICs. The pre-regulator's innovative architecture improves thermal performance compared to traditional two-stage buck designs and supports a wide range of input and output voltages, resulting in outstanding efficiency that is ideal for compact applications with high power densities, making it ideal for demanding power solutions.
"With the release of our latest Intel Core hyperprocessors, we are committed to providing our customers with the best possible battery life experience," said Josh Newman, vice president and general manager of product and platform marketing for Intel's Client Computing Group. The collaboration with Renesas will deliver solutions that will bring unmatched energy efficiency to the next generation of innovative mobile platforms.”
Tom Truman, vice president and general manager of high-performance computing capabilities at Renesas, said, "We have partnered with Intel to develop AI-powered mobile solutions designed to make the benefits of cutting-edge technology accessible to every user. This product demonstrates the depth and breadth of our power technology and our ability to lead on emerging market trends.”
At present, power management integrated circuits are developing in the direction of being more efficient, smarter, and more reliable. The performance of power management integrated circuits will be further improved by adopting advanced semiconductor processes and packaging technologies, as well as continuously optimizing circuit structures and control algorithms. At the same time, with the continuous development of emerging technologies such as artificial intelligence and the Internet of Things, power management integrated circuits will also usher in more technological innovation and application opportunities.
