I'm looking at TPS62230 to potentially replace a 1.35V LDO. I saw that the internals look like a typical DCDC, so I experimented with modifying the feedback node with a resistor divider to achieve 1.35V. It looks to work and doesn’t show any dynamic load issues in simulation.
My only question:
Is this an acceptable way to modify the part? Does it have any limitations that would prevent this circuit from working effectively? I didn’t see anything in the D/S referring to this capability.
