Description
The IRF6691PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packag-
ing to achieve the lowest on-state resistance in a package that has the footprint of a SO-8 and only 0.7 mm profile. The
DirectFET package is compatible with existing layout geometries used in power applications, PCB assembly equipment and
vapor phase, infra-red or convection soldering techniques. Application note AN-1035 is followed regarding the manufacturing
methods and processes. The DirectFET package allows dual sided cooling to maximize thermal transfer in power systems,
improving previous best thermal resistance by 80%.
The IRF6691PbF balances industry leading on-state resistance while minimizing gate charge along with ultra low package
inductance to reduce both conduction and switching losses. This part contains an integrated Schottky diode to reduce the Qrr
of the body drain diode further reducing the losses in a Synchronous Buck circuit. The reduced losses make this product ideal
for high frequency/high efficiency DC-DC converters that power high current loads such as the latest generation of micropro-
cessors. The IRF6691PbF has been optimized for parameters that are critical in synchronous buck converter’s SyncFET
sockets.
