Does TI have AC/DC LED driver with integrated FET in their portfolio?

Early there was LM3448 and TPS92310, but as I understand they are absolute now.

The LM3448 is obsolete, but the TPS92310 is not although it is a controller. The LM3445 is the same device as the LM3448 but it in also a controller. But it only requires one extra FET and the rest is the same. If triac dimming is not required the LM3444 is a stripped down version of the LM3445.

Clinton, Thanks for the answer.
In previous post I mistype, I mean LM3448 and TPS92311.
According to your repply for a moment TI doesn't have any AC/DC LED driver with in tegrated power transistor.

That is correct. All of the AC-DC LED drivers with integrated FETs have been obsoleted. They both have companion chips that are controllers which offers more flexibility. That may have some role in the decision.
