I have a Qualcomm charger that I would like to output a constant 12V/ 20V. I know phones and tablets that support QC protocols set D+ and D- for different voltages (as in picture below). I'm wondering if the attached below picture will allow me to get say +12V from the charger safely and is it a electrically sound idea? Or should I just regulate from the VBUS itself?
