TPS50601A-SP: Designing TPS50601A-SP with Webench tool

Part Number: TPS50601A-SP
Other Parts Discussed in Thread: TPS50601-SP

Hi team, 

My customer had the following question around simulating TPS50601A-SP in Webench. 

They  have correctly set the voltage divider (Rtop = 10kOhm, Rbottom = 20.3kOhm) since the ‘A’ version has a new voltage reference equal to 0.804V instead of 0.795V for the TPS50601-SP. Nevertheless, the tool tells them that their actual voltage is 1.19V instead of 1.2V.

If they try to set the bottom resistor to 19.6 kOhm, then they get 1.2V.

Meaning that the voltage reference is actually 0.795V and not 0.804V like it should be.

Is there a risk that the TPS50601A-SP model for the Webench tool is actually the same as the TPS50601-SP ?

Here is how they've computed that Rbottom should be 20.3kOhm if Rtop is 10 kOhm :

Can you please assist here!

Thanks, 

Obinna.
