We are using the TPS62823 in a device that relies partly on battery power. when we are not powered from our main supply we need to have as low a current as possible. during testing of our power supply we noticed that total quiescent current draw was VASTLY higher than we were anticipating.
our power supply :
during testing we removed R13 in the schematic above to isolate just the power supply section to see how much power was being drawn without the rest of the device connected. we see ~50uA is being consumed by the power supply section alone, with no load applied:
this is unacceptably high and leads us to believe that something is wrong, either the circuit is not behaving as we believe it should or we have selected the wrong device for this application.
Do you have any input on this?
