Is there a KiCad symbol and footprint for the L6725A?
Yes. The symbol is EasyEDA_Cloud:L6725ATR 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 L6725A?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the L6725A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L6725A?
JLCPCB lists it as part C1530364, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L6725A?
Parts like it in the library: the TL494ID by Texas Instruments, the SG2525AP013 by STMicroelectronics, the TL494CD by Texas Instruments and the SG3525AP(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
