Pic of board below ., it’s from a grooming brushless blower drier . 3 transistors have been removed, ready for replacement.

Might be this part, maybe trace a couple of pins over to the mosfets for confirmation.....

Many thanks, physical dims are spot on and tracing seems to confirm, but how do I know the internal spec is the same ? Did you find it as compatible ?

Guess on my part given you need mosfet drivers for that application,
and 4 digit part number rung a bell in my fat head.

You could power one of those parts up on bench, and confirm functionality
sort of.

Maybe this is a half-bridge driver.

Though the marking is not the same. The datasheet says IR2103 but your pic says IT2103. However, the pinout is the same. You can use IR216 as an alternative.

Hello, Thank you. Very good workmanship. I am satisfied. This board is a half-bridge driver for a switching power supply. Best regards, Sergey.
