Ronv, that's exactly what I'm searching for ! But still can't get it Uu, and I dont have spice
DerStrom8, I tried this:
Do you see that the FET is not activated? Even if I connect it directly to the 5V source ! I also tried placing a button, and I get this error:
I simplified the schema (see my last post pls), now I send the pulse directly to the FET.
That's what I did, but still I can't activate de mosfet. I tried with the IRF3711 fet, and also with a generic one.
Thanks for the calculator. What mosfet shall I use then? It's incredibe hard to pick the good one :confused:
As I said before, if I use a generic npn bipolar instead, it works fine, but even if I try with a generic nmosfet it doesn't work. I also tried with a 10V amplitud pulse, but it seems it...
I'll show you the basic circuit that I want to made. Is a dc-dc boost 1.2V - 5V to 12Vout, 100W out. The bipolar was for making a drive for the mosfet, and as you said, placing R2 wasn't a good idea. My main problem is that I can't activate the mosfet.
The pulse that I'm sending is a periodic...
Hi
Nice remark, I tried placing a resistance between the mosfet and the ground, but the mosfet is still off. If I replace the mosfet by a bipolar it works perfectly...uu
