Hi Given,

Hi Given,

If the 4.7k resistor stays NC i don't see a problem with the schematic. If you do end up populating the 4.7k resistor there is a good chance the part will not turn on. I would recommend increasing that resistor to get the part above the EN threshold of 1.7V. Otherwise the schematic looks good.

Best Regards,
Mark
