App note: Paralleling power MOSFETs in switching applications


Application note from Alpha and Omega semiconductor on proper design of circuit and PCB layout to balance parallel MOSFETs. Link here (PDF)

This paper discusses issues involved in paralleling MOSFETs in high-power, high-frequency switching applications. It investigates root cause problems such as unbalanced voltage and current by taking a closer examination of PCB layouts and important circuit design parameters for driving paralleled MOSFETs
