  RE: WEBENCH® Tools/TPS7A4001: LDO output voltages controlled by DAC

  Hi Koho, To verify this function, it's better to use a DC source to replace the DAC during debugging. You may then run DC transfer characteristic sims by varying the VG1. Please see the results also in the screenshot. As you can see, when VG1 is...
