Overview

The SG3525AP is a DC DC Converter made by STMicroelectronics in a SOIC-16 package with 16 pins. -55℃~+150℃@(TJ) 2 400kHz 8V~35V SOIC-16 DC-DC Converters 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. JLCPCB lists it (part C19884).

Questions

Is there a KiCad symbol and footprint for the SG3525AP?

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 SG3525AP?

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

Where is the SG3525AP datasheet?

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

Where can I order the SG3525AP?

JLCPCB lists it as part C19884, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SG3525AP?

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.
