Mil gracias.
Ya se que se trata de un regulador para pasar de 12v a 5v, si no consigo la información completa le meto un dc dc genérico de los chinos.

Thanks.
After a good photo posted by Vectras in spanish forum it is marked as TS3 in SMD SOT23-6. I can find that TMI3253S is the IC. SY8113 silkprint is WC....
I'm going to check booth datasheets.
It appears to be equivalents IC's.

Checked, SY8113BADC is the same that TMI3253S.
Fully compatible.
But be careful TMI3253 and TMI3253T aren't.
Different pinout and specifications.
