    Hi Terry,

    Thank you for considering the TPS40210-Q1. The device should be able to support your application, but the SEPIC model of the Webench has limited coupled inductor selections. If you reduce your load current to 1.9A, it will generate a model. Then, you can use it as a start point, and make some small tweak to get 2A load. Meanwhile, I am going to pass your question to our Wenbench experts, and see if the Webench capability can be expanded.


    Thanks,

    Hi Terry,

    We have fixed the issue regarding design creation of TPS40210-Q1 ( For Vin =5-20 Vout =18, Iout=2). The fix will be available on ti.com by end of next week. Meanwhile I have created the design with your input condition and printed the report for you (below attached). Please let me know if this helps.
