P Channel and N Channel MOSFETs in Switched Mode Power Supply Applications

MOSFETs have been the chosen transistor technology in most Switched Mode Power Supplies (SMPS) since the mid 1980’s. MOSFETs are used as the main switching transistor as well as to improve efficiency ...

P-Channel Power MOSFETs Approach N-Channel Performance

The source voltage of a P-channel device is stationary when the device operates as an HS switch. Conversely, the source voltage of an N-channel device used as an HS switch varies between the low side ...
