DDR5 LRDIMM
M88P5010/5000 (DDR5 PMIC)
M88P5010/M88P5000 is a JEDEC-compliant Power Management IC (PMIC) for DDR5 Server DIMM applications. The chip contains four DC-DC buck converters and two low-dropout regulators (LDO, 1.8 V and 1.0 V), and supports I²C/I3C serial bus to meet different application requirements.
The PMIC is designed to provide power support for other on-DIMM chips such as DRAM, RCD, DB, SPD Hub, and TS. The CPU implements power management by communicating with the PMIC via the SPD Hub. M88P5010 is designed for low-current RDIMMs, while M88P5000 is designed for high-current RDIMMs and LRDIMMs.
The left image shows the application of PMIC on the DDR5 LRDIMM as an example.
