WEBENCH® Tools/LM5022-Q1: Webench BOM anomalies ??

Part Number: LM5022-Q1
Other Parts Discussed in Thread: LM5022

Tool/software: WEBENCH® Design Tools

Good day Forum,

I have interesting  in doing a boost design using the LM5022

Using Webench as my refr-design tool  design link here >> https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=6459BBC600BD0D9F

I bought a blank dev board from digikey Part 296-45760-ND

I found anomalies in the Webench Design refr BOM compare to the schematic provided by Webench

Other than attempting to go through all the datasheets to determine the correct values,

 I was hoping that webench is a tool to short-circuit the effort and provide reliable info

Referring to the BOM as per the reference design, here are the variations in component  values -

 Value for-                 Schematic Value            BOM PartNumber (digikey)                BOM Properties

Ccomp2                    56.0nF                            1206A562JA = 5600pF = 5.6nF          56.0nF

Ccs                            1.0nF                              04025A101JA =100pf                           1.0nF

I hope someone from Ti / Webench can respond

Thanks!

Gerhard

    These are typos, either in the schematic values or in the BOM list part numbers. I am checking with our Webench expert and will get back a confirmation of the correct info for you. Please check back.

    Hi Gerhard,
    In this specific case, the value for the components recommended is correct but the recommended part number has an issue because of a typo in our database. This issue is specific to AVX parts in the design. We are working on a fix for this and will update our database as quickly as possible. In the meantime, you can go to select alternate part and select a non-AVX capacitor and the part number recommended should be correct.
    Regards,

    Hi All,

    Thank you for the replies.

    You confirm that -

    1.  The schematic value is correct

    2. Problems with AVX Part#

    I have selected Alt comp, not from AVX.

     The correct Part# now follows what the component value is on the schematic.

    Thank you.
