P8910

PMIC with Step-Down Switching and LDO Regulators

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.

Features

• 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

• Three LDO regulators: VBias, VOUT_1.8V,

VOUT_1.0V

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.

• Automatic switchover from VIN_Mgmt input supply

to VIN_Bulk input supply

• Error injection capability

• Error log registers

• Write protect mode of operation

The PMIC is available in small 5 × 5 mm form factor in

VFQFPN package with enhanced solder joint

reliability and thermal dissipation.

• Independently programmable output voltages,

power up and power down sequence for switch

regulators

• Input and output power-good status reporting

mechanism
