I am trying to use the TPS7H1101-SP to output a 1V, 3A power for my board. The input power of the TPS7H1101-SP is 1.8V. From the datasheet, I know that the CS pin needs to be connected to Vin though a resistor. And we can calculate the value of the resistor by the formula: Rcs=(Vin-Vcs)/Ics.
My question is, In my case, if I want to make CS pin high, how should I choose the value of Vcs?
