[FAQ] TPS62901: How do you select the MODE/S-CONF pin resistor?

Part Number: TPS62901

What is the accepted resistor tolerance for the MODE/S-CONF pin resistor on the TPS6290x device? Can I use a value greater than 118k Ohm?

    To choose the correct Smart Config setting it is required to use “E96 Resistor Series, 1% Accuracy, Temperature Coefficient better or equal than ±200 ppm/°C" because the Smart Config mode selection is digitally controlled.

    Another important requirement is that the resistor value is selected from Table 7-1 in the datasheet for the desired operating mode. Any resistor values larger than 118k or not specified in the table may result in an incorrect operating mode/behavior.
