I wanted to make 5V output Buck converter, see the capture 2, there was a big change when I changed the BJT's Base Voltage. It just looks like Transistor-drop simulation.
Other Captures hold base voltage as 3V, and just changed inductor 22mH or 22uH(maybe)
or Is just a problem of BJT's library?
I think I'll use ST microelectronic's 2N2222. I knew only this NPN.
