Fairchild Semiconductor’s 100V MOSFET Provides 50 Percent Lower RDS(ON) for Power Supply Designs

Fairchild Semiconductor provides designers of isolated DC-DC applications a 100V MOSFET with 50 percent lower RDS(ON) and excellent FOM for higher efficiency in power supply designs. The FDMS86101, a 100V MOSFET packaged in 5mm x 6mm MLP Power56 packaging, is designed using Fairchild’s advanced PowerTrench® process that minimizes on-state resistance, while maintaining superior switching performance and ruggedness. This proprietary process technology provides the industry’s lowest RDS(ON) (8 milliOhms) compared to current solutions with the same gate charge and allows the FDMS86101 to improve conduction losses without suffering the penalty of a higher gate charge. Ethernet, blade servers and telecom applications are transitioning from a 12V to a 48V power supply and the need for switches that optimize efficiency is increasingly important.
