Overview

The TPS5403D is a DC DC Converter made by Texas Instruments in a SOIC-8 package with 8 pins. -40℃~+85℃@(TA) 1 1.1MHz 1.7A 100uA 3.3V 4.5V~28V Buck Buck Built-in Fixed No SOIC-8 DC-DC Converters ROHS.

PCBKit's library has its KiCad symbol (Regulator_Switching:TPS5403, 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. 1,888 are in stock at JLCPCB (part C962080). 5 open-source boards in 4 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the TPS5403D?

Yes. The symbol is Regulator_Switching:TPS5403 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 TPS5403D?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the TPS5403D datasheet?

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

Where can I order the TPS5403D?

JLCPCB lists it as part C962080, with 1,888 in stock; the sellers' links on this page open their listings.

What can replace the TPS5403D?

Parts like it in the library: the XL1509-3.3 by UMW, the XL1509-3.3E1 by XLSEMI, the LM2576D-3.3RG by HANSCHIP semiconductor and the AP1509-33SG by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the TPS5403D?

5 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
