TPS40304 not working

Hello all,

I used Webench to make the circuit of a DC/DC with:

- 14-14V Input.

- 7.6V Output.

- 20A Output.

But... it doesn't work, seems to have all pins with 0V but EN is about 1.5V. I made 2 different PCBs but not working.

The schematic is this one:

Can be a problem with Diode? Attached is the file I got from Webench.

6471.WebenchReportsServlet.pdf

In the output I only have about 0.3V

Best Regards!
