I tried a simple design in Webench:
Vin of 7.0 to 14.0 V
Vout of 3.3V
Iout of 5.0A
Ambient 30A
Then I click Start Design.
Webench does the Initialization, then does 'Calculating' while displaying a moving circle of lines. It stays here forever. I've used these parameters in the past, so something has changed with Webench.
If I do the default that the program starts with of:
Vin of 14 to 22 V
Vout of 3.3V
Iout of 2.0A, it works (of course if these parameters didn't work, you guys would probably have noticed by now).
I suppose I could do a trial-and-error to figure out which parameter is causing the software to choke, but I was hoping you guys could figure it out and fix it.
