Hello all,

Been away for a while, hope everyone is well. I've got a question in regards to the LM2596 INVERTING switcher. I'm brain frying over a "shutdown", or rather a "start up" circuit for this rig. Can you fine folks check out these datasheets real quick and let me know if I'm over-thinking things (which would not be abnormal for me ).
I would like to turn ON the switcher with +12vdc...
It appears to me that these two datasheets conflict each other?
