title: Renesas RAA215300 Power Management Integrated Circuit (PMIC)
maintainers:

description: |
The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for
32-bit and 64-bit MCU and MPU applications. It supports DDR3, DDR3L, DDR4,
and LPDDR4 memory power requirements. The internally compensated regulators,
built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell
battery charger provide a highly integrated, small footprint power solution
ideal for System-On-Module (SOM) applications. A spread spectrum feature
provides an ease-of-use solution for noise-sensitive audio or RF applications.
This device exposes two devices via I2C. One for the integrated RTC IP, and
one for everything else.
