![]() ![]() Achieving this streamlines the circuit and effectively lessens the all round cost. You can easily drive a P-channel high side switch using an ordinary level shifter circuit (voltage level changer). On the other hand, this may not be the situation with a P-channel MOSFET. These drivers demand a separate power source, while the transformer load can on occasion go through incompatible circumstances. Therefore, here operating an N-channel MOSFET necessitates an independent gate driver such as a bootstrapping circuit, or an arrangement involving a pulse transformer stage. When used in a high side switch application the source voltage of an N-channel MOSFET happens to be at an increased potential with regard to ground.
