Hi, I am looking for a TRIAC dimmable LED driver, we would like to sell this project in India where we have 230VAC power supply and 50Hz frequency, do you have any suggested and tested circuit so that we can start developing the solution ? Also I heard about a saying that all TRIAC dimmers cannot be used with drivers (I request you to comment on this)

    Check out the LM3445, LM3447, LM3448, or the TPS92075 for switchers. There is also the TPS92411 and TPS92410 that are linear based with floating switches. They are all designed to be triac dimmable and there are reference designs and EVMs available for most.
