Hello,
We're reusing our TPS65023B PMIC circuit to power noise sensitive circuitry, so we want to give ourselves the option to use a bench top supply for one or more rails.
Please see included schematic.
Is it OK if we use a bench top supply for one of the jumpers and pull the inductor (e.g., apply 1.1V to J21 and pull L3)? Should we also disable the DCDC#_EN in this case?
Any guidance or concerns that you can provide will be appreciated.
Thank you,
Bob
