Here is a project from youtube buck boost converter

and im lookingforward to make my own. But problem is cant find the right value inductor for it. The guy in the video says "for my prototype curcuit I'll use 0.03mH inductor". Is it possible to change inductor value?
I happen to have a inductor or i guess 3uH which is 10 times less than used in his project.

 

If you are using everything else the same then the inductor should be the same too.
I don't know what chip it is using but usually there are formulae in the datasheet for getting a correct value for the inductor (and other components).

This tells me that you have no idea what you are doing. Inductor values aren't chosen at random. A 3μH inductor will give you a boost of around 10millivolts. If you want to have a successful build of someone elses project, then USE HIS PARTS! Especially if you don't know how to modify things.

I have little bit of knowledge about buck boost converters.
Tell me one thing is coil32 software useful to calculate inductors or required inductance?
