Also those converters can easily get shorted to the ground. --- End quote --- Ah, I forget that these have very low resistances :palm: I measure 4 ohm on one side and 0.3 ohm on the other side of the resistors. |

Resistance may be fine depending on what power rails those are. I'd expect converter IC to be dead if a ferrite bead in its input failed open/burned. The issue is that if upper mosfet (between Vin and out) inside the IC fails short first, it may take out (overvolt) the load as well. |
