Hi,
I have Arduino Pro Mini (3.3V) connected to a DC/DC converter (58V -> 5V, 2A) (connected to RAW / GND.) The problem is that the Arduino keeps restarting every few seconds. When I use a standard 5V power supply, it works fine. The output voltage of the converter seems to stay put around 5.03V and doesn't seem to drop, at least not that I can see with my multimeter. Could you help me understand why this is happening? Is there anything I can do to get it working?
Maybe post a link a) to the 58v to 5v converter and b) to the 58v power source.
One of these may have a shutoff if insufficient power is being drawn.
If that is the case, you could, as an experiment, try putting an additional load over the 5v output (say 100 Ohms - could get warm) to see if that makes it more stable.
If the supply is a steady (regulated) 5V then should you maybe be connecting to 5V instead of Raw.

Not with a 3.3V Pro Mini, Vcc = 3.3V on those.

Oops, missed that little nugget, Thanks

That was it, I changed the power source and everything's back to normal. Thank you, I appreciate the help.
