I'm using the ADP5300 and 2 alkaline cells to power my board.
I have a question regarding a special case :
When programming/debugging the mcu, the board is powered from the debug probe and a voltage is applied at the output of the ADP5300, with no input voltage present.
According to the datasheet, the maximum SW to PGND voltage is −0.3 V to PVIN + 0.3 V.
So this is not fulfilled if an output voltage is applied and PVIN is left floating or connected to ground.
Should I expect any trouble here ? Is there something I should do to avoid damaging the converter ?
