The RAA225019 from Renesas is a highly configurable Power Management Integrated Circuit (PMIC) designed for Intel IMVP9.2 Lunar Lake applications. It requires an input voltage of 2.7 - 4.5 V. This PMIC integrates power MOSFETs and current-sensing circuitry, enabling high switching frequencies for efficient operation in small form factors. It features six configurable phases distributed across three outputs, two SVID rails and one auxiliary rail, with flexible phase configurations to optimize performance based on application needs. This PMIC uses Renesas’ ripple regulator technology, achieving fast transient response and minimized output capacitance. It includes an integrated low-dropout (LDO) regulator with a power gate bypass option that enhances its adaptability.  

This compact PMIC excels in light load efficiency by naturally stretching periods in discontinuous conduction mode (DCM). It provides comprehensive monitoring via an I2C bus, offering input voltage, output current, temperature, and PSYS telemetry while enabling integrated compensation to reduce both bill of materials (BOM) costs and PCB space. This PMIC is available in a wafer-level package that measures 5.04 x 3.74 x 0.525 mm and is ideal for low-power mobile device applications.
