Overview
The LM3578AM is a DC DC Converter made by Texas Instruments in a SOIC-8 package with 8 pins. 0℃~+70℃@(TA) 1 2V~40V 750mA Boost、Buck、Inverting Buck、Boost Built-in No SOIC-8 DC-DC Converters ROHS.
PCBKit's library has its KiCad symbol (Regulator_Switching:LM3578, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C201561). 2 open-source boards in 2 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the LM3578AM?
Yes. The symbol is Regulator_Switching:LM3578 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM3578AM?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM3578AM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3578AM?
JLCPCB lists it as part C201561, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM3578AM?
Parts like it in the library: the XL1509-5.0E1 by XLSEMI, the XL1509-ADJE1 by XLSEMI, the XL1410E1 by XLSEMI and the MC34063AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM3578AM?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
