Re: [TCML] De-Qing diode

[Ed Phillips <evp@xxxxxxxxxxx>]

   OK.  Certainly the voltage on the switched end of the inductor rises 
to twice the supply voltages [losses neglected] and the cathode of the 
diode is hooked to the output capacitor charged to twice supply voltage 
with respect to ground.  When the switched end of the inductor is at 
ground the reverse voltage across the diode will be the capacitor 
voltage which is indeed twice the supply voltage.

   I've never understand where the 'De-Quing notion came from because 
there's no Q involved.
