Dear sir,

We are working on led project "DC LED tubes"

- 60cm, power 10w, input DC volt range 35 to 75V, LEDs volt 76V, LEDs current max 120mA .
- 120cm, power 18w, input DC volt range 35 to 75V, LEDs volt 76V, LEDs current max 240mA .

Kindly recommend a suitable driving IC and send me the full datasheet in English

waiting for your reply,
Your quick response is highly appreciated,

Dear sir

kindly be informed that this driver will be used in DC tube & we need it as small as possible.

Then, we need the led driver ic to be maximum of 8 pins package.

kindly recommend another suitable one.

Thanks & Best Regards

The TPS40211 could possibly do it, but you would need to clamp the VDD voltage with a zener/resistor so you would be burning some extra power. All of our 75V boost/buck-boost LED driver devices are in larger packages similar to the TPS92690/91.
