Hi Alpesh,

Please look at the TPS92410 device. I believe it is the only device we have that is able to support that voltage range.

It does have dimming capabilities.

HI Julian,

Thanks for your support.

But we also need to support AC input up to 305VAC with analog or PWM dimming in single chip for low BOM cost.

please let us know any other option for single chip selection.

Alpesh

Hi Alpesh,

The TPS92410 device also supports analog dimming from an input voltage from 0 to 3V.

Hope this helps!
