Unfortunately I can't find the following component on the internet. No matter what I type, I can't find anything.

5A TI 51240
3C TI 51240?

The two ICs are broken on both boards. It happened when the plus and minus were swapped.

The board runs at 12 V or 24 V.

The pinout looks similar to the TPS54240, perhaps it's a 54240 and the printing has rubbed off the second digit?

    \$\begingroup\$ This looks correct +1, compare the image at LCSC. I suspect the markings were maybe more exploded off than rubbed off. \$\endgroup\$ Commented Apr 3, 2024 at 16:51
