Hello!

I'm using WEBENCH for developing AC-DC power supply device.

I've chosen scheme with UCC28703, but I can't see the simulation button (nor temperature nor electrical simulation)

Does WEBENCH allow to simulate AC-DC power designs?

Does anybody have SPICE-model of UCC28703 (or other UCCxx)?

Thanks in advance!

Can you take a screen shot for the problem?
When i choose UCC28703 in webench, it worked well.

Thank you for your response.

Here is my first step on the ti.com home page:

Then I press "Start Design" button and get to this screen:

As you can see I have no "Simulation" button and therefore I have no access to simulation data.

I hope I brought it clearly.

Hi Kirill,
If you click on the "charts", you would see the result of "efficiency, duty cycle, IV Curve, standby power dissipation".
And you can find more data when you click "view other charts" in the charts view.
you couldn't expect a transient simulation in the webbench.
It offer a start for the real design.

Thanks.
What is about SPICE-models? Are they exist?

There is minor differeces between UCC28700 and UCC28703.
There is spice model for UCC28700.
