International Rectifier offers power MOSFET's for DC-DC synchronous buck applications

Image of International Rectifier's FastIRFET Power MOSFETThe 25V FastIRFET™ family of innovative is ideal for 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 industry-standard PQFN package that delivers benchmark power density for discrete DC-DC converters. The family includes the IRFH4201 that offers on-state resistance (RDSon) as low as 0.7 milliOhms, 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 3.3 mm PQFN packages that feature an environmentally friendly, lead-free, and RoHS compliant bill of materials.

Features and Benefits
  • Low RDSon (<0.95 mΩ) results in lower conduction losses
  • Low thermal resistance to PCB (<0.8°C/W) enables better thermal dissipation
  • Low profile (<0.9 mm) results in increased power density
  • Industry-standard pinout results in multi-vendor compatibility
  • Compatibility with existing surface-mount techniques results in easier manufacturing
  • MSL 1, industrial qualification results in increased reliability
  • Synchronous rectifier MOSFET for synchronous buck converters
  • Secondary synchronous rectifier MOSFET for isolated DC-DC converters
  • Active o-ring and hot swap
  • Battery-operated DC motor inverters
