Hi ,
I have used the recommended design in the Datasheet and have used in the feedback resistor value 10k and 57.6k for generating around 5.4 V.
and used 3.3u H with DC resistance of 140mOhm and Capacitors two 10uF X7R. I am also using a Diode at the output before the load.
I can see ripple of around 200mV with load of around 40mA. I know TPS562201 works in PFM and has lower regulation in lower load region.
So I used TPS562208 which shows 38mV of ripple in Workbench simulation but I can see around 122mV.
It would be nice if you can suggest some improvements.
Hi
Thanks for the reply. It certainly helped 
. But I can still see some ripple and gitters after the diode.
As mentioned before we have a diode in series after the inductor and capacitors. Does a diode in series at the output before load effect the regulation.
After diode
Before diode
The chopping you see, is transmission happening. And that has worst impact after the diode. As the current changes from 30mA to 100mA during transmission.
so I wanted to understand if the regulator is impacted by the diode or its just the drop of the diode.
Measurement is done in AC coupling mode
