Techniques

Description

The IRF6601 combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM 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. The DirectFET package allows dual sided cooling to maximize thermal transfer
in power systems, IMPROVING previous best thermal resistance by 80%.

The IRF6601 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 IRF6601 has been optimized for parameters that are
critical in synchronous buck converters including Rds(on), gate charge and Cdv/dt-induced turn on immunity. The IRF6601
offers particularly low Rds(on) and high Cdv/dt immunity for synchronous FET applications.
