Tool/software:
Hello,
I am designing the circuit using WEBENCH tool as reference. However, it shows error when I modify the input range from 13V to 15V. According to the datasheet, the input range is from 4.5V to 65V. May I ask for some support on this?
Best Regards,
Alice
Hello Alice,
Thank you for reaching out. The webench model for the LM5181 has limited transformer options in its library. So, pease use our design calculator to help you design. You can find it at https://www.ti.com/tool/download/LM5181DESIGN-CALC. Remember to choose the right part from the pull down menu located close to the upper left corner of the spreadsheet ( see a snapshot below).
Hope this helps.
Best Regards,
Youhao
