A linear preregulator driver in conjunction with an external depletion mode N-MOSFET provides initial controller power. Once the bootstrap supply is functional, the preregulator is shut down to conserve power.
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.
