描述

The P8910 is a highly integrated, highly efficient PMIC with programmable output voltage power for all DDR5 server DIMM modules. It includes four step-down switching output regulators and three Low Drop Out (LDO) output regulators. The Renesas PMIC5010 is a small server PMIC to support low current DDR5 modules and applications and it is fully compliant with the JEDEC DDR5 PMIC5010 (JESD89) specification. The PMIC is powered from two input power supplies (VIN_Mgmt and VIN_Bulk) from the system board to power its switching and LDO output regulators.

The P8910 has numerous advanced protection schemes to protect itself as well as to protect entire BOM contents of the DDR5 server DIMM modules. The PMIC offers write protect operation to defend against malicious attacks, and has an advanced I3C bus that can operate at maximum speeds of 12.5MHz with low voltage I/O operation.
