Tool/software:

Hi,

I want to use WEBENCH to simulate LM25180 design.

Unfortunately I can't change the output voltage (default 5V);

When I set current to 0 I get

When I do it from main page like this,

(BTW I can't select isolated output.)

I get this error

    Hi Thomas,

    Thank you for designing with our products.  First, please note that Webench does not enable the simulation for this part.  So, please use our design calculator to help you to create a design, and if you wish, you can simulate the circuit in TINA or Pspice.  You may find the TINA and Pspice model under the LM5180 product folder.

    When using the design calculator, please note that there is a pull-down menu in which you can choose a proper part of the family.  If none is able to support your max power, then please take a look at the LM25185 or LM5185.

    Hope this helps.

    Thanks,

    Youhao
