Comparison between P-channel and N-channel MOSFETs in an application

When used as high-side switches, N-channel MOSFETs require an isolated gate driver or a pulse transformer. The driver needs an additional power supply, while the transformer can sometimes produce incorrect conditions. On the other hand, P-channel MOSFETs can be easily driven as high-side switches with a simple level-shifter circuit, simplifying the circuit and reducing the overall cost.
