Abstract

A novel 25V silicon trench power MOSFET optimized for fast and high efficient switching with record Ron*Qg and Ron*Qoss figure-of-merits is reported. A dual channel structure with two different gate oxide thicknesses allows reducing the body diode conduction losses by up to 50% and enables 95% DC-DC conversion efficiency.
