MP2122AGJ-Z, Achieving least voltage output!

DC-DC Power Converters
1

The buck converter I have chosen is ‘MP2122AGJ-Z’ for my application.
The application supports from 0.58V to 0.63V and I observed that the least it can support is 0.608V
I am assuming to achieve this output i can simply tie output to feedback with 0E(Rtop) and Rbottom as Not Fitted.
Please can you confirm is my method correct? if no, please suggest how can I achieve mentioned 0.608V. Will the current be same???

Thanks,
Samuel

Hello Samuel,

For the MP2122A the feedback voltage node is 0.608V, so yes all you would need to do is ensure that Rtop is 0V and Rbottom is not fitted as you said.

You can also add the required resistor ratio that would achieve the desired output, but that would dissipate power unnecessarily.

I know it has been some time since you’ve posted. Let us know if there have been any updates at all.
