Other Parts Discussed in Thread: TPS92411

Hi TI Experts:

Currently for the TPS92411, I only able to find the Dimmable AC Linear Floating Switch LED Driver Reference Design at TI website.

http://www.ti.com/tool/PMP6022

But the application that need to be done is non-dimmable.

Is there any circuit recommendation for this?

Or is there any modification that i need to do to change the reference design from dimmable to non-dimmable?

based on TPS92411.....

Please advice.

Thanks,

Br,

It will work absolutely fine for non dimming applications as it is. Having said that it may be possible to reduce the component count a little if dimming is not needed. But I am not 100% familiar so I will forward this to the right person. I believe he may be out currently so a response could be delayed.

I have forwarded this to the best person but he is out until Monday. Hopefully he can get back to you then.

Hello,

RF1 can be replaced with a fuse (or if you don't need a fuse it can be removed and shorted)

C1, R3, D24, R5, D26, D27, and C4 can be removed.

It will work fine as the circuit is for a non-dimming application.

Thanks,
