WEBENCH® Tools/WEBENCH-POWER-DESIGNER: HTML5 Webench can't design negative supplies, Mobile webench won't load

Part Number: WEBENCH-POWER-DESIGNER

Tool/software: WEBENCH® Design Tools

Hi,

I use a browser that doesn't have flash, and for security reasons I can't install it. 

I've used the HTML 5 Webench at https://webench.ti.com/wb5/WBTablet/index.jsp 

1. Open https://webench.ti.com/wb5/WBTablet/index.jsp

2. Use the default settings, but change the output voltage to -3.3V

3. Click on "Open Design" on any of the recommended solutions.

4. It throws an internal server error

I tried using the mobile version too, at https://webench.ti.com/wbmobile/

    It appears that parts of my post were truncated. The directions and links all appear to be correct.

    TLDR:

    HTML5 Webbench works fine for positive supplies, but fails when loading negative supply designs.

    Mobile Webbench gives bad gateway errors.

    Hi John,

    We were able to duplicate the issue with negative output voltage in the HTML version for tablet. The bug has been assigned and we are fixing it for now. The mobile should be working fine now. If you still see any issue with the mobile version, would you please send us the URL that you encounter the gateway error issue.

    Regards
