Hi guys,
I'd like to know if someone can help me out here.
I am designing a buck converter. Right now I am on the control side. In the figure bellow you can see the error voltage behavior.
http://s9.postimg.org/d34lpfgnz/111111.pngThis error voltage is subject to a step in the load.
What I want to know is if it is possible to shrink or to reduce the dynamic range of this error volta. I don't know if I can call it dynamic range. What I mean by dynamic range is the total variation of the voltage.
The reason I want his is because this voltage will be driving a comparator and the comparator can't support such high voltage at the input. It goes to triode region. (in corners specially).
How can I do this?
Kind regards.
