TPS54538: Looking for DCDC Converter with Specific Ripple Parameter

Hi,

We're reviewing this and will respond soon.

Hi Manish, 

I managed to finish the job in the meantime.
Webench is now working for me. It was not working three days ago.
The best it found was the LMS3655AMRNLR.
It came out to 300uV Vp-p.
While Webench was down, I played around with some competitive converters.
One started with 100uV Vp-p, as I simulated in their tool.

Then I added a ferrite filter to the output and got it down to 7uV Vp-p.

I also fine-tuned the switching parameters. Dynamic load states.
The idea was to have:

Any DC-DC converter.

100uV Vp-p
Supply voltage 24V
Minimum output voltage 5.5V
Maximum output voltage 6V.
These forks were not allowed to be exceeded.
Load current 1mA and 3.5A peak current.
I'm writing to let you know I'm finished. And I wanted to thank you for trying to help.

I also learned that the 1uH 2.4mV choke coil at the input of the converter, responsible for reducing EMI, causes interference at that frequency to travel to the converter output.

I simply copied the schematic from Workbench to the LMS3655 simulator.

So, in reality, I was using Workbench, in the end, and put a competitive converter into the webench schematic. 

Then I replaced the input EMI filter coil with a different one and added a filter at the output.

and have 10uV Vp-p

Thank you anyway.

The correct word is Webench, not workbench.
