Hi,

The datasheet has a design process step by step, please follow that, you can ask if some components you do not how to design.

You can also contact your local TI sales office and local technical support to request reference design.

The below is a design based on Webench, where do you think you get not required results?

Hi,

Webench does not provide simulation to every device. Your message did not clearly state the simulation is the issue that is why I asked to contact your sales. Please make sure describe your issue specific.

On the simulation, you need to use PSpice model, and PSpice for TI.
