    Thank you for this video, it was very interesting. It would be interesting to look at your flyback converter as well.

    Hi! Really nice video. I'm trying to adjust the current in low value region (0-30mA) but I enter into an area of instability and the voltage drops. Do you have any suggestion for this problem? My goal is to regulate the current from 0 to 100%

      Without looking at what you have going on my first thought it consider voltage across the sense resistor and the voltage at the feedback pin on the boost converter. Are they reasonable values at 30mA? Its going to be impossible with my circuit to get the full range of current values working.
      Youre going to have to make a table with voltage, current, and resistor values to find what range is going to work for you. For example, under some combination of inputs the regulator can not output a voltage to make everything work. That's where I would start at least.

      @@carolinaworkshop7091 great, thanks for your reply. yes, as you say, at low current there will not be an acceptable voltage. Now I'll try to write the table. A thousand thanks!
