The TPS53832A is D-CAP+™ mode integrated step-down converter for DDR5 on-DIMM power supply, which 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 7 A (or 3.5A + 3.5 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 TPS53832A is packaged in a thermally-enhanced 35-pin QFN and operates from -40°C to +105°C.
