We would like to test the system by applying power directly to the power rail which is normally powered with the TPS25982.
In the schematic below the power would be applied at +VIN (output of TPS25982) instead of J3
1. Is it OK to have up to 16V at the output with no power applied at the input?
2. Do we need to disable the device to make sure it is switched off in this situation?
3. What if we allow a small amount of reverse current (reverse diode and resistor)
