Hi, I'm trying to get a design in WEBENCH using the LM25117 device for a 24V Input, 12V/12A output, however, after entering these parameters, Webench fails!

Any clues as to why?

Thanks in advance.

Hello,

Thanks for sharing the error message. I also tried to create a design and see the same thing. I will forward your error to the Webench team.

In the meantime you can also use the calculator tool to help choose components. You can find this in the Tools Tab of the product folder.

Best Regards,
Katelyn

Hi Katelyn. Thanks for confirming the issue.
At least I know I'm still sane :)

Quick update, I have found that if I enter an ambient temperature that is negative (i.e. -20°C), then the design will load!!! Obviously, with this setting, any ambient temperature related graphs etc will be wrong,
