Description: What's inside a better USB charger - Alza power double charger Q200C / Qualcomm quick charge 3.0 with one USB and one USB C port. I'm examining the internals, partially reverse engineering the schematic and explaining how does it work. Including the autopsy of the switching transformer, oscilloscope measurements and explaining a flyback switching power supply with a synchronous rectifier.
