Buck Converter l Low Conduction and Switching Losses l Compatible with existing Surface Mount Techniques l 100% Rg tested ISOMETRIC MX l Footprint compatible to DirectFETTM Applicable DirectFET Outline and Substrate Outline (see p.7,8 for details) l l SQ SX ST MQ MT MX MP Description The IRF6894MPbF combines the latest HEXFET(R) Power MOSFET Silicon technology with the advanced DirectFET TM packaging to achieve the lowest on-state resistance in a package that has the footprint of a SO-8 and less than 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 IRF6894MPbF balances industry leading on-state resistance while minimizing gate charge along with low gate resistance 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 microprocessors. The IRF6894MPbF has been optimized for parameters that are critical in synchronous buck converter's Sync FET sockets.
