Questions

Is there a KiCad symbol and footprint for the UCC29950D?

Yes. The symbol is EasyEDA_Cloud:UCC29950D and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the UCC29950D?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the UCC29950D datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the UCC29950D?

JLCPCB lists it as part C2872759, with 0 in stock; the sellers' links on this page open their listings.

What can replace the UCC29950D?

Parts like it in the library: the TL494IDRG by HANSCHIP semiconductor, the SG2525M/TR by HGSEMI, the SG3525A by IDCHIP and the UCC28063D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
