Overview
The SG3525 is an AC DC Controllers & Regulator made by Gcore in a SOP-16 package with 16 pins. DIP-16 AC-DC Controllers and Regulators ROHS.
PCBKit's library has its KiCad symbol (Regulator_Controller:SG3525, from KiCad's library) and its footprint (Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 1,787 are in stock at JLCPCB (part C5157689). 8 open-source boards in 7 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the SG3525?
Yes. The symbol is Regulator_Controller:SG3525 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 SG3525?
SOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the SG3525 datasheet?
Gcore publishes it: the Datasheet link on this page opens it.
Where can I order the SG3525?
JLCPCB lists it as part C5157689, with 1,787 in stock; the sellers' links on this page open their listings.
What can replace the SG3525?
Parts like it in the library: the FAN4802SMY by onsemi, the NCP1615C2D by onsemi, the NCP1615CD by onsemi and the NCP1615DD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SG3525?
8 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
