Texas Instruments TPS53832A Low-Current PMIC
Texas Instruments TPS53832A Low-Current PMIC provides a D-CAP+™ mode intended for DDR5 on-DIMM power supplies. The TPS53832A offers VDD, VDDQ, and VPP voltages to the DRAM chips on the DIMM module with configurable current capability. The high-current rail of the device can be configured to 2-phase or two outputs. This delivers up to 7A (or 3.5A + 3.5A) current with D-CAP+ mode control. The converter also employs internal compensation for ease of use and reduces external components.
The TI TPS53832A PMIC features a full set of telemetry, including input voltage, output voltage, and output current. Overvoltage, undervoltage, overcurrent limit, and over-temperature protections are also provided.
The TPS53832A is available in a thermally-enhanced 35-pin QFN package and operates from -40°C to +105°C.
