IR Introduces the IRF6708S2 and IRF6728M DirectFET® MOSFET Chipset Tailored for Cost Sensitive DC-DC Applications



International Rectifier has introduced the IRF6708S2 and IRF6728M 30 V DirectFET® MOSFET chipset tailored for cost sensitive 19V input synchronous buck applications. 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. The IRF6708S2 and IRF6728M feature IR's latest generation 30 V 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 The devices are RoHS compliant and datasheets and application notes for the devices are available on the International Rectifier website at
