Requirement for Webench

I will write our requirement for WEBENCH function in the following.

-Please add Min and Max value to Op Vals list. especially about Vout value.
I think Webench list typ value now, however device FB reference voltage has tolerance, thus we would like to confirm Min and Max value include tolerance of reference voltage and FB resistor tolerance.

-Please reflect the above Op vals to design report.

-Please list Vout value down to three decimal places at operating value of design report.

-We would like to set Fsw , soft start time and current limit value in the parameter setting screen at the following figure. Then we hope that set parameter is reflected to schematic component value.

Best Regards,
Kohei Sasaki

  • Kohei-san,

    Thank you for the suggestions. I will pass them on to the developers for review. Please remember that the tolerances you have referred to are not the only tolerances that will effect the accuracy of a power supply.

    You can currently set the FSW and SS time for the design here:

    The current limit is set based on the current requirement from the initial input screen. We do not let the customer change this value, however, the customer can edit the resistor and use a custom component value if desired. I would prefer to use the value calculated by WEBENCH® for the design so that I do not have to rework the calculations.
