Description
The RRG5321x 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 PMIC5020 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 RRG5321x has numerous advanced protection schemes to protect itself and the entire BOM's contents of the DDR5 server DIMM modules. The PMIC offers secure mode operation to defend against malicious attacks, and has an advanced I3C bus that can operate at a maximum speed of 12.5MHz with low-voltage I/O operation.
The PMIC is available in a small 5 × 5 mm form factor in 35-VFQFPN package with enhanced solder joint reliability and thermal dissipation.
