Hi,

We are planing to use TPS54202 for power supply of the ADC(ADS131M04) input voltage with following spec,

- Input voltage : 24V

- Output voltage : 3.3V

I'm considering using a 10uH inductor and a 10uF output capacitor. I would like you to confirm if this value are appropriate for my calculation.

Thanks

Hi Bobby

The 10uH inductance is ok, For the Cout, I would recommend you reserve position for one more 10uF cap . You can test the load transient performance after the board assembly. and you can decide if need to place it after the test.

Thanks and best regards.
