Tool/software:
The LM27762 datasheet Section 8.2.2 Detailed Design Procedure encourages you to use webench.ti.com/.../quickview.jsp WEBENCH fails to find it, even if you manually add the part number.
If you then try and report this on the WEBENCH feedback link, it fails too.
This attempt to make life more convenient actually wastes time while you try different ways to make it work, assuming that you are the cause of the error. Please fix or remove from the datasheet.
