Why TI official website doesn't provide the LM26420-Q1 average model?

I had try used the WEBENCH to get the loop response curve, but I can't add new passive component in the schematic to make it conform to my actual apply, so the simualtion results is not I needed.

The WEBENCH is very slow, why not provide a local install version?

Hi Zhang,

We try to provide evaluation tools for many of our devices. In this case, WEBENCH should be your primary tool. I see from your post that you are having issues changing the BOM components. I verified and this should not be an issue. You should be able to select alternate components for the 2 channels. What is the exact issue that you are having with WEBENCH? Can you provide more details so we can help you out?

Hi Nikhil Gupta ,

I am not clear how to change the schematics in webench still. Below is my L26420X transient simulation schematics,since the ti website not provide average modle, so I can't get the loop respose in pspice.

Cloud you edit the schematic in webench and share to me?
