WEBENCH® Tools/LMR33630: Design cannot be created only for LMR33630B SOIC and Iout=0.3A

Hi team,

My customer considers to use LMR33630BDDA and he is using Webench for the design.

When he set Vinmin=Vinmax=12V, Vout=8V, Iout=0.3A, Temp=30℃ then design can not be created as attached.

In case of other load current like 0.2A, 1A etc, design can be created successfully.

Also, in case of other package (WSON), there is no problem even if it's same input voltage, output voltage, output current.

Is this just due to error of Webench?

Best regards,
