|
|
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.
