Is my schematic of the TPS54240 buck converter correct?
There are a few mistakes.

BOOT and PH connections are swapped.
The catch diode is on the wrong side of coil.
Compensation pin is missing a capacitor. If it is not needed, it is a good precaution to draw it, so you have a place for a capacitor if you need it, so you don't have to manufacture new boards just because you don't have a place for an important capacitor.
