Thanks, but it's not: I just verified it's indeed a TPS71550.

Why on earth the TPS71550 is marked T48 is beyond me! But it is, 100%, I ev=
en just soldered one on one of those old PCB's I had bought it for, and it =
works. :)

I hardly have a use for them anymore though, damn me how many components I =
bought that I have now a problem to think a use for. :/
