I've just put together my first busk converter with a LMR16006Y-Q1. http://www.ti.com/lit/ds/symlink/lmr16006y-q1.pdf
Here is what it looks like on the scope. The Pink signal is unloaded, the other is with a 90 ohm load. It seems noisy to me. I think I need to make some changes. But I'd like to get input from someone else.
It's laid out on a PCB almost exactly like this, with the only difference being that the Feedback is tapped straight into the inductor output pad rather than stretching all the way to the output after the cap. I'm not sure if that will really mak a difference. :
