The IRF8313PbF incorporates the latest HEXFET Power MOSFET Silicon Technology into the
industry standard SO-8 package. The IRF8313PbF has been optimized for parameters that are
critical in synchronous buck
operation
including Rds(on) and gate charge to reduce both conduction
and switching losses. The reduced total losses make this product ideal for high efficiency DC-DC
converters that power the latest generation of processors for notebook and Netcom applications.
