Description

The IRF6637 combines the latest HEXFET® power MOSFET silicon technology with advanced DirectFET^TMpackaging 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,

when 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 IRF6637 balances both low resistance and low charge along with ultra low package inductance 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

operating at higher frequencies. The IRF6637 has been optimized for parameters that are critical in synchronous buck operating from 12 volt

bus converters including R_DS(on)and gate charge to minimize losses in the control FET socket.
