International Rectifier introduced the IRF6706S2PbF and IRF6798MPbF DirectFET MOSFET chipset that offers efficiency for 12 V input synchronous buck applications including servers, desktops, and notebooks. The IRF6798MPbF Medium Can DirectFET provides on-state resistance (RDS(on)) of <1 mOhm. The device features a monolithically integrated Schottky diode that reduces losses associated with body diode conduction and reverse recovery losses to further enhance the overall performance of the solution. The IRF6798MPbF offers ultra low gate resistance (Rg) of 0.25 Ohm to eliminate Cdv/dt related shoot through. The IRF6706S2PbF Small Can DirectFET also features low charge and low RDS(on)to reduce switching and conduction losses, and low Rg for fast switching.
