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 cell17 battery charger provide a highly integrated, small footprint power solution18 ideal for System-On-Module (SOM) applications. A spread spectrum feature19 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, and22 one for everything else.23 24 Link to datasheet:25 https://www.renesas.com/in/en/products/power-power-management/multi-channel-power-management-ics-pmics/ssdsoc-power-management-ics-pmic-and-pmus/raa215300-high-performance-9-channel-pmic-supporting-ddr-memory-built-charger-and-rtc26 27properties:28 compatible:29 enum:30 - renesas,raa21530031 32 reg:33 maxItems: 234 35 reg-names:36 items:37 - const: main38 - const: rtc39 40 interrupts:41 maxItems: 142 43 clocks:44 description: |45 The clocks are optional.
