IR's FastIRFET™ Family Delivers Industry Leading Efficiency for DC-DC Synchronous Buck Applications

EL SEGUNDO, Calif.--(BUSINESS WIRE)-- International Rectifier, IR® (NYS: IRF) , a world leader in power management technology, today announced the introduction of the 25V FastIRFET™ family ofinnovative power MOSFETs for DC-DC synchronous buck applications including advanced telecom and netcom equipment, servers, graphic cards, desktop, ultrabook and notebook computers.

The FastIRFET™ family features IR's latest generation silicon in an industry standard PQFN package that delivers benchmark power density for discrete DC-DC converters. The family includes the IRFH4201 that offers on-state resistance (RDS(on)) as low as 0.7 milliOhms, and the IRFH4210D and IRFH4213D monolithic FETKY® devices designed to reduce ringing and further improve system efficiency.

"The advanced 25V FastIRFET™ MOSFETs offer industry leading power density for discrete high performance DC-DC switching applications," said Stephane Ernoux, Director of Marketing, IR's Power Management Devices Business Unit. "These devices complement our integrated SupIRbuck®, PowIRstage® and power block platforms to offer designers a broad array of high performance DC-DC options."

Optimized for 5V gate drive applications, IR's FastIRFET™ devices work with any controller or driver to offer design flexibility while delivering higher current, efficiency and frequency capability in a small footprint. The devices are available in industry standard 5x6 and 3.3x3.3mm PQFN packages that feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
