Questions

Is there a KiCad symbol and footprint for the L6728?

Yes. The symbol is EasyEDA_Cloud:L6728TR and the footprint EasyEDA_Cloud:DFN-10_L3.0-W3.0-P0.50-BL-EP2.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6728?

DFN-10(3x3), with 11 pins. Its footprint is drawn on this page.

Where is the L6728 datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the L6728?

JLCPCB lists it as part C6974599, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L6728?

Parts like it in the library: the L6728D by STMicroelectronics and the SY7901DBC by Silergy Corp. Check their datasheets: a part that fits the footprint may still differ in its ratings.
