3 Description
The TPS53840 is a D-CAP+? mode integrated stepdown
converter for DDR5 on-DIMM power supply
in servers fully compliant to Jedec PMIC5020. It
provides VDD, VDDQ and VPP voltages to the
DRAM chips on the DIMM module with configurable
current capability. SWA and SWB can be configured
to be either a dual phase output (20A) or 2 single
outputs (10A each), while SWC is a single phase rail
capable of 11.5A. 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, output
current and output power. Protection features include
input and output over voltage, input and output
undervoltage, buck overcurrent limit, and die over
temperature.
TPS53840 with its significantly higher current
capability than JEDEC PMIC5000, and configurable
Auto power on or VR_EN pin, is suitable for CXL
memory module applications.
The TPS53840 is packaged in a thermally-enhanced
35-pin QFN and operates from -40°C to +105°C.
