Is there a KiCad symbol and footprint for the TPS54316MPWPREP?
Yes. The symbol is EasyEDA_Cloud:TPS54312PWPR and the footprint EasyEDA_Cloud:HTSSOP-20_L6.5-W4.4-P0.65-LS6.4-BL-EP-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TPS54316MPWPREP?
HTSSOP-20-EP, with 21 pins. Its footprint is drawn on this page.
Where is the TPS54316MPWPREP datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TPS54316MPWPREP?
JLCPCB lists it as part C2865167, with 10 in stock; the sellers' links on this page open their listings.
What can replace the TPS54316MPWPREP?
Parts like it in the library: the LM2596S-3.3(UMW) by UMW, the LM2596S-3.3 by GR, the LM2596R-3.3 by HTC and the XL2596S-3.3E1 by XLSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
