Hello,

We have several devices for MR16 application

Dimmable MR16: LM3492 fantastic dimming performance with low component count

Non-dimmable (>4W):TPS92560 low output ripple current and easy to implement

Non-dimmable (<4W):TPS92511 low cost, small size and good performance

For your case, you can choose TPS92560.

Please go to TI’s website for detail information and reference designs.

Regards,

Victor

Please kindly advise if the TPS92560 has the dimmable function or not? we are targeting to load 36V COB, and enable dimmable function. （ELV，Triac dimmable）, if TPS92560 not workable, do you have any other Model proposed?
