WEBENCH® Tools/LM5161: LM5161 flybuck configuration for 3V3 with dual supply

Part Number: LM5161

Tool/software: WEBENCH® Design Tools


I am trying to simulate LM5161 for a fly back configuration where I need one Isolated power supply of 3V3@150mA and another non-isolated one at 3V3@1.2A

As for suggested configuration here it is designed for 12V at 500mA each.

I have tried downloading simulation model from component page

But, I am unable to edit components as there properties are missing (like transformer and LM5161). So, its difficult to simulate for 3V3.

Another thing, which I have tried is using WEBENCH POWER DESIGNER to design it. But, It feels like it is lacking a lot of components as compares to this circuit here

This is the suggested circuit by WEBENCH:

Any help will be really appreciated.
