Description
The IRF6611 combines the latest HEXFET® power MOSFET silicon technology with advanced DirectFET^TM packaging to achieve the lowest
on-state resistance in a package that has the footprint of an 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 IRF6611 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 IRF6611 has been optimized for parameters that are critical in synchronous buck operating from 12 volt
bus converters including R_DS(on), gate charge and Cdv/dt-induced turn on immunity. The IRF6611 offers particularly low R_DS(on) and high Cdv/
dt immunity for synchronous FET applications.
