Data sheet:
The TPS53840 is a D-CAP+™ mode integrated step-down 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.
