WEBENCH® Tools/LM25088: WEBENCH errors out on generating 19VIN, -12VOUT/3A design

Hi Roger,

I forwarded your enquiry to the product expert. We will need to check if the LM25088 is fully enabled for inverting buck-boost operation in WEBENCH. Should be no problem for the IC.

Regards,
Tim

Thanks Tim. Roger, please share your 2.8A design so I can take a look.

New WEBENCH - Go to EXPORT, then click the share button. You can get a public link from that share popup.

Classic WEBENCH - Click Share Design - Share with Public - Get new shareable link

Hey Sam,

Sorry for the delay in getting back to you. I was out over Thanksgiving week, and just getting caught back up.

I am unable to figure out how to share the design.

Using the new WEBENCH - POWER DESIGNER, I cannot find the share button when I go to the EXPORT page.

I am unable to bring up the Classic WEBENCH to even try it. Don't know why.

I am attaching the pdf for the design.

I can send you the exported html file for the page if that will help.

That is all that I can provide right now.

The basic design input parameters for the DC/DC design are:

VIN Nominal: 19V (18.5Vmin - 19.5Vmax)

VOUT Nominal: -12V

IOUT Nominal: 2.8A

IC: LV25088-2 or -1

Regards,

Roger Perry

Roger,

See share button location circled in green below. Sometimes I get errors depending on which browser I'm using. Chrome seems to work well for me.

The issue you're seeing is in WEBENCH not allowing something so I'd like to make sure I'm checking the issue with your exact settings.

Jeff,

OK. Chrome works a lot faster and better than IE or Firefox.
