Good luck! There is another version of this IC with 2 more pins which provides error reporting as well. Now onto the arduous process of eliminating 120hz hum.
Ahh good point! The inductor claims to be good up to 1amp. I plan to draw roughly 0.7-0.5 amps at 13volts in the final application. As for the LED, it is purely for testing as it was available and capable of handling the power.
Jim, you are 100% correct!
I had put the incorrect voltage divider in!
Thank you so much for your help (and to everyone else who commented.)
R1 was 1K, I changed R2 to 10k to achieve roughly 13vdc (my end goal) and everything is working perfectly now.
