Could it be a TNYxxx from Power Integrations?

I suspect that is probably the case -- a part of the flyback converter power supply. The remaining part of the logo looks like that of PI.

Recently replaced one of these bad boys on a cloth drier control board. Check if it has only 7 legs.

Sure it's a power ic switch but since it is exploded i can't know exactly what reference series, i guess Top223 or 224! Unless if there is photo of this board.

I check now TNY series
TNY266 P or G10 W15 W6 W9.5 W
TNY267 P or G13 W19 W8 W12 W
TNY268 P or G16 W23 W10 W15 W
maybe I will try TNY268!

I think the TOPxxx parts are a better fit.

Can you find the missing piece of the IC inside the case?

Could it be TOP242-250G ?

Hello
Thank you Mr Fzabkar. I found in my stock parts the TOP244pn. I removed up the exploded one and I put this top244 works perfectly. But unfortunately there is no voltage in output even I reload factory parameters, so no output voltage!
