1 / 1 page  P8910 PMIC with Step-Down Switching and LDO Regulators R10DO0003EU0100 Rev.1.00 Page 1 Mar 15, 2022 Short-Form Datasheet © 2022 Reneas Electronics The P8910 is a highly integrated, highly efficient PMIC with programmable precise output voltage power solution for all DDR5 Server DIMM modules, with four step-down switching output regulators and three LDO output regulators. The PMIC is fully compliant to the JEDEC DDR5 PMIC (PMIC5010; Low Current PMIC) 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 to protect entire BOM contents of 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 speed of 12.5MHz with low voltage I/O operation. The PMIC is available in small 5 × 5 mm form factor in VFQFPN package with enhanced solder joint reliability and thermal dissipation.
