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.

Pin 5 is straight to ground for instant-on. As this is going to be used to drive and amplifier IC, a time delay on may be better?

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. I have included a picture for those who...
