FastIRFET(tm) Family Supports DC-DC Synchronous Buck Apps

International Rectifier announced the introduction of the 25 V FastIRFET family of innovative 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 mΩ, and the IRFH4210D and IRFH4213D monolithic FETKY® devices designed to reduce ringing and further improve system efficiency.

Optimized for 5 V 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 5 x 6 and 3.3 x 3.3mm PQFN packages that feature an environmentally friendly, lead-free and RoHS compliant bill of materials.

Pricing for the FastIRFET™ family ranges from US $0.32 for the IRFH4234 to US $0.96 for the IRFH4210D in 10,000-unit quantities. Production orders are available immediately.
