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
