TI TPS53830RWZR Integrated Step-Down Digital Converter For DDR5 On-DIMM Power Supply

Product Description Of TPS53830RWZR

TPS53830RWZR is D-CAP+™ mode integrated step-down converter for DDR5 on-DIMM power supply. TPS53830RWZR 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 TPS53830RWZR converter also employs internal compensation for ease of use and reduce external components.

The TPS53830RWZR 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.

TPS53830RWZR is packaged in a thermally-enhanced 35-pin QFN and operates from -40°C to +125°C.
