EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the IRF6708S2 and IRF6728M 30V DirectFET® MOSFET chipset tailored for cost sensitive 19V input synchronous buck applications such as notebooks.

The IRF6708S2 Small Can and IRF6728M Medium Can devices reduce component count by 30 percent to drastically reduce overall system cost. The new DirectFET MOSFETs feature low charge and on-state resistance RDS(on) to minimize conduction and switching losses. The IRF6728M also features a monolithically integrated Schottky that reduces losses associated with body diode conduction and reverse recovery.

“By providing a highly efficient, cost effective solution for cost sensitive DC-DC switching applications with the assurance of the DirectFET’s superior thermal characteristics, the IRF6708S2 and IRF6728M chipset represents excellent overall value,” said Omar Hassen, executive director, Low Voltage DirectFET Products, Enterprise Power Business Unit.

The IRF6708S2 and IRF6728M feature IR’s latest generation 30V MOSFET silicon. In addition to low RDS(on) and charge, the new devices leverage the low parasitic resistance inductance and superior cooling ability of the DirectFET package
