Overview

The P8900 PMIC is a power management IC (PMIC) designed for typical DDR5 RDIMM, DDR5 LRDIMM, and DDR5 NVDIMM applications. The PMIC features four step-down switching regulators and three LDO regulators. The P8900 PMIC is designed to support up to 15 Watts of power. It is powered from VIN_Bulk input for switching regulators and VIN_Mgmt input for the rest of the PMIC. The P8900 PMIC supports selectable interface (I²C or I³C) to fit various application environments.
