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.


  • VIN_Bulk input supply range: 4.25V to 15.0V
  • VIN_Mgmt input supply range: 3.0V to 3.6V
  • Four step down switching regulators: SWA, SWB, SWC and SWD
  • Programmable dual phase and single phase regulator for SWA and SWB
  • 3 LDO regulators: VBias, VOUT_1.8V, VOUT_1.0V
  • Automatic switchover from VIN_Mgmt input supply to VIN_Bulk input supply
  • Independently programmable output voltages, power up and power down sequence for switch regulators
  • Input and output power good status reporting mechanism
  • VIN_Bulk input supply protection feature: input over voltage
  • Multi Time Programmable Non-Volatile Memory
  • Programmable and DIMM specific registers for customization
  • General Status Interrupt function
  • Flexible Open Drain IO (3.3V, 2.5V, 1.8V or 1.2V or 1.1V) or Push Pull IO (1.2V or 1.1V) support
