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