RAA215300 PMIC

RAA215300 from Renesas is a new high-performance, low-cost 9-channel PMIC designed for 32-bit and 64-bit MCU and MPU applications. This highly integrated PMIC (Power Management IC) is optimized for RZ/V2L and RZ/G2L microprocessors (MPUs) designed for AI-enabled applications. 

The new RAA215300 PMIC comes with a wide range of features including internally compensated regulators, built-in Real Time Clock (RTC), 32kHz crystal oscillator and coin cell battery charger that provide a highly integrated, small footprint power solution ideal for System-On-Module (SOM) applications. It includes six buck regulators, three LDOs and a coin cell/supercap charger and supports DDR3, DDR3L, DDR4 and LPDDR4 memory power interface. The high level of integration increases system reliability due to fewer system components needed on the board.

RZ/V2L and RZ/G2L MPUs when paired with the new RAA215300 PMIC can enhance the performance and offer ease of design. Additionally, the high integration and rich feature set makes it a great choice for consumer, industrial and SoM applications.
