The RAA215300 is a high Performance 9-Channel PMIC supporting DDR Memory, with Built-In Charger and RTC. 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.
