Normally off mosfet
Web11 de out. de 2016 · A third approach is to use a depletion mode MOSFET or a JFET but that's a lot trickier because you have to come up with a negative voltage to turn the transistor off. It does work in the absence of any significant voltage supply though. Another disadvantage is that power devices are unavailable in P-channel type. WebAnswer (1 of 5): Good luck with your project! I’m not sure I’d be comfortable designing a switch mode voltage converter based on a YouTube video, but I guess you use …
