From the project

TPS5430 based DC-DC Buck Converter Module with parts from JLCPCB

This is a small DC-DC Buck converter board based on the TPS5430 from TI specifically intended to be ordered from JLCPCB with few "extended parts". This was a practice project for me, so please feel free to point out any issues.

Vin = 5.5V..36V Vinmin = 1.15 Vout (see Datasheet Section 8.2.1.2.8.1) Vinmax = 8.33 (Vout + 0.5) (see Datasheet Section 8.2.1.2.8.1) Vout = 1.8V/3.3V/5V/12V (choose via solder bridge) Reverse polarity protection with AO3401A p-MOSFET 3A (hold)/6A (trip) polyfuse input protection The board can be powered with a 2.1mm/5.5mm "standard" Arduino compatible barrel jack…
