TPS51916RUKR Description

Short technical summary and product information.

The Texas Instruments TPS51916RUKR is a specialized integrated circuit designed to provide a complete power supply for DDR2, DDR3, DDR3L, and DDR4 memory systems. It integrates a synchronous buck controller for VDDQ and a 2-A sink/source tracking LDO for VTT, along with a buffered low-noise reference (VTTREF).

 

Key electrical specifications include an output voltage range of 0.7 V to 1.8 V and a conversion voltage range of 3 V to 28 V. The device supports selectable switching frequencies of 300 kHz, 400 kHz, 500 kHz, or 670 kHz, and features D-CAP™ or D-CAP2™ modes for fast transient response. It boasts 0.8% VREF accuracy and 20-mV VTT accuracy.

 

This component is housed in a 20-WQFN (3x3 mm) package, suitable for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The TPS51916RUKR is designed for applications requiring efficient and stable power delivery to memory modules, offering features like OCL/OVP/UVP/UVLO protections and a powergood output.
