IR Presents New IRF6607 DirectFET MOSFET

December 12, 2002 by Jeff Shepard

International Rectifier Corp. (IR, El Segundo, CA) introduced the IRF6607 DirectFET MOSFET designed for synchronous MOSFET switch applications in high-frequency, synchronous buck converters. A buck converter using a single pair of IRF6607 DirectFET MOSFETs can deliver up to 30A per phase at 2MHz with 77 percent efficiency. The devices are suitable to power gigahertz Intel and AMD microprocessors for notebook computers, high-end desktop PCs and servers.

The 30V IRF6607 is housed in an SMT package with dual-sided cooling in an SO-8 footprint, and provides improvements in conduction and switching losses. Leveraging the low, die-free, package resistance of the DirectFET package, the IRF6607 offers an ultra-low on-resistance of 2.7 milliohms. The low gate charge and gate-to-drain charge combine with a package inductance 70 percent lower than an SO-8-packaged MOSFET, enabling low switching losses in the megahertz frequency range.

The high thermal conductivity of the DirectFET package dissipates power easily. Using a heatsink to remove heat through the top of the package reduces PCB area around each MOSFET, shrinking circuit size and reducing PCB trace inductance to eliminate undesirable switching losses. DirectFET devices have low power dissipation and high thermal conductivity, enabling 30A per phase at 2MHz with only two DirectFET MOSFETs.

The new IRF6607 is available now. Pricing begins at $1.69 each in 10,000-unit quantities.
