I am using Arduino and Controlling FAN which works on 48v. so i am using 2 power supply smps in my design. One for Arduino that 5V smps and another for FAN that is 48V smps.
I want to use single power supply in my design that is of 48Vdc. I was looking for a buck converter that will take 48V as input and 5V as output.
But most of the buck converters are required 30 to 38V as an input.
Any suggestions.

It doesn't seem hard at all to find converters that can handle 48V input. This is a random example: https://www.amazon.com/Converter-Step-Down-Waterproof-Transformer-Voltage/dp/B07YCQTSXQ

Is there something I am missing?

Thanks @Bordodynov and @Yaakov .
I missed some informartion in my first post. I was looking for buck converter IC which will do the job.

I am thinking to use LM5058 from ti.
