DerStrom8 Super Moderator Sep 29, 2014 #22 pabloncho , did you see AG's post? audioguru said: The load is only 1 ohm and the Mosfet is an old one. When the Mosfet switches then the voltage boost will not be much. Click to expand... At least change the load resistance.

That may work in a sim, but is likely to cook a 1.2V battery in practice .

K kubeek Well-Known Member Most Helpful Member Sep 30, 2014 #25 If you need to run from as low as 1.2V, then you need a mosfet that can switch with such low gate voltage, and there arent many and even less with high enough current, so bjt might be a better choice here.
