High current PMIC for DDR5 server DIMMs

The TPS53830 is D-CAP+™ mode integrated step-down converter for DDR5 on-DIMM power supply.

It provides VDD, VDDQ and VPP voltages to the DRAM chips on the DIMM module with

configurable current capability. The high-current rail can be configured to 2-phase

or 2 outputs to supply up to 12 A (or 6 A + 6 A) current with D-CAP+™ mode

control. The converter also employs internal compensation for ease of use and reduce

external components.

The converter provides a full set of telemetry,

including input voltage, output voltage, and

output current. overvoltage, undervoltage,

overcurrent limit, and over-temperature

protections are provided as well.

The TPS53830 is packaged in a thermally-enhanced 35-pin QFN and operates from -40°C to +125°C.
