13*fff8f6b0SBiju Das  The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for
14*fff8f6b0SBiju Das  32-bit and 64-bit MCU and MPU applications. It supports DDR3, DDR3L, DDR4,
15*fff8f6b0SBiju Das  and LPDDR4 memory power requirements. The internally compensated regulators,
16*fff8f6b0SBiju Das  built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell
17*fff8f6b0SBiju Das  battery charger provide a highly integrated, small footprint power solution
18*fff8f6b0SBiju Das  ideal for System-On-Module (SOM) applications. A spread spectrum feature
19*fff8f6b0SBiju Das  provides an ease-of-use solution for noise-sensitive audio or RF applications.
20*fff8f6b0SBiju Das
21*fff8f6b0SBiju Das  This device exposes two devices via I2C. One for the integrated RTC IP, and
22*fff8f6b0SBiju Das  one for everything else.
