TPS51716 datasheet in PDF form, 1.14 MB, apparently a different edition of the Texas Instruments document for this memory power controller. The IC generates the VDDQ supply through a buck stage plus the VTT termination rail and reference used by DDR memory. It is handy when measuring a board with no memory voltage: the pin table, enable logic and typical schematic show where to probe and what each pin should read. Check the revision history in the document if values differ between copies.
