Hello,
I would look at the TPS92074 if there is no Triac dimming. The datasheet also shows interface to an NTC thermistor. If there is Triac dimming the TPS92075 would work. You could also use the LM3444.
Thanks,
Hello,
If you are rectifying 120 VAC you must not care about power factor correction. A simple solution would be the LM3444. If you are using the UCC27714 what topology are you using? As for 230 VAC input with the LM3444, that would just be choosing the…
Other Parts Discussed in Thread: TPS92310 , LM3444 , LM3445 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.
LM3444 does not have a PSpice or TINA-TI model. LM3444 is supported by WEBENCH which can help you generate the application for your needs but there is no simulation enabled for this device in WEBENCH either.
If you are interested in using this device…

Other Parts Discussed in Thread: TPS92075 , LM3444 , LM3445 , TPS92410 We like to design 120VAC LED dimmable driver for our white light LED lamps (PAR30- MR16). You will recommend driver and design. We prefer internal dimming using simple microcontroller…
Hello,
Does this need isolation? Is there a limitation on the overall LED stack voltage? Is there dimming involved? What is the power level? Is a two stage solution preferred or single?
Non-isolated I may consider PFC boost and then buck, boost using…

Hello,The TPS92074 may not be the right solution if 90-277 VAC in your input
A simple solution without ZCD for a buck could be the LM3444 however you will not have the best line regulation since there is no compensation loop. Perhaps the UCC28810/11…
