WEBENCH® Tools/TPS56428: Simulation does not start

Part Number: TPS56428

Tool/software: WEBENCH® Design Tools


I simulate TPS56428 on VIN=5V, VOUT=3.3V, IOUT=4A condition, however it is not executed as below.


Why is it?

Best Regards,


  • Hi,

    I think WEBENCH set a duty limit here,~65%. But it should be okay with higher duty , as the max duty is around 83% , based on the(1- minoff time / cycle time ).

    if you need a WEBENCH quick results, you can "input" 5.2Vin to check.
