New Medium Voltage Power MOSFETs for Synchronous Rectification

摘要

This paper will present the new Fairchild medium voltage MOSFETs. The latest shielded-gate powerrnMOSFETs can dramatically reduce both on-resistance and gate charge that usually are in trade-off.rnWith soft body diode characteristics, the new power MOSFETs enable to reduce voltage spikes whichrncause additional losses in the snubber circuits. For better system efficiency and power density, therncharacteristics of new power MOSFETs, called PowerTrench? MOSFET are presented and comparedrnto other power MOSFETs available in the market. The benefits of these new power MOSFETs arernshown in synchronous rectifier of target application.
