Driving and Layout Requirements for Fast Switching MOSFETs
The objective of this paper is to describe the driving methods and layout requirements for fast switching MOSFETs. Power MOSFET technology continues to evolve towards higher cell density for lower on-resistance. However, there are silicon limits for a significant reduction in the on-resistance with the conventional planar MOSFET technology due to the exponential increase in onresistance with increasing breakdown voltage. One approach to overcome this limitation is to use Super-Junction technology in high voltage power MOSFETs. This technology dramatically reduces both on-resistance and parasitic capacitances. With smaller parasitic capacitances, these Super-Junction MOSFETs have extremely fast switching characteristics and as a result, reduced switching losses. This switching behavior occurs with greater dv/dt and di/dt that affects switching performance through parasitic components in the devices and on the printed circuit board and influences the EMI performance of the entire system.
