Datasheet for the Texas Instruments TPS51716, a complete DDR2/DDR3/DDR4 memory power solution combining a synchronous buck controller for VDDQ with a sink/source VTT LDO and buffered reference. This 1.23 MB PDF covers pinout, electrical characteristics and application circuits. Repair technicians use it to identify pins, check expected voltages on VDDQ, VTT and VTTREF, understand S3/S5 control inputs and diagnose a dead memory rail on laptop and desktop boards. Compare the package marking on the chip with the datasheet.
