Hello all,
If you look at Figure 1 here
https://www.maximintegrated.com/en/app-notes/index.mvp/id/2031
I am wondering why the diode to ground is necessary.
If the switch is closed, the inductor is charged, and then when the switch is opened, the inductor energy actually has nowhere else to go except to the capacitor (and load).
So why bother having the diode to ground?
When the switch is closed, the circuit already is grounded with the capacitor.
