Be sure to always begin the title of your post with the part number. We support many LED drivers in the LED driver forum, so LED driver by itself is rather uninformative.

I'm not sure that the TPS61165 is the best option for driving a single LED. What is your input voltage range?

Dear Mam

The input voltage is 1s li-ion battery i.e(3.3v to 4.25v ).And can i use LM-4040 i.e Shunt Voltage Reference as a PWM generator

I would recommend a TPS630xx buck boost converter, such as TPS63000. There is an LED driving app note on the product page.

You need to begin a new post in the appropriate forum for support on the LM device.

Dear Mam

In TPS63000 you are using LM4040 can you tell the use of this.
