  I done some further investigation, and yes seems really to be more a Switching noise instead of AC Ripple: Measurement has been made with the tip-ring to shorten as soon as possible the ground path. Trace #1 (Yellow): Ouput , coupling in AC Trace#2…

  In a boost, if Vin>Vout, the PWM controller will stop switching and the Vin will pass through to Vout, and produce Vout = Vin -VF -Vdrop, where VF is the forward drop of the rectifier diode, and Vdrop is the voltage drop across the boost inductor and…
