Power MOSFETs exhibit reduced top-side thermal impedance.

Press Release Summary:

Supplied in SON package with 5 x 6 mm footprint, DualCool(TM) NexFET(TM) devices dissipate heat through top of package for high-current DC/DC applications. Each single-phase, 35 A synchronous buck converter MOSFET features packaging technology that reduces thermal impedance to top of package to 1.2°C/W. Dual-side heat sinking enables up to 50% more current through FET, allowing use with higher-current processors without increasing end equipment size.

Texas Instruments Unveils Power MOSFETs with Reduced Top-Side Thermal Impedance to Cool High-Current DC/DC Applications

DualCool(TM) NexFET(TM) power MOSFETs with innovative package offer up to 80 percent higher power dissipation and up to 50 percent more current in a standard footprint DALLAS -- Texas Instruments Incorporated (TI) today introduced the industry's first family of standard-footprint power MOSFETs that dissipate heat through the top of the package for high-current DC/DC applications. DualCool(TM) NexFET(TM) power MOSFETs reduce end equipment size, while providing up to 50 percent more current through the MOSFET and improving thermal management over other standard-footprint packages. See: www.ti.com/dualcool-pr. This new family of five NexFET devices allows computing and telecom system designers to use higher current processors with expanded memory while saving board space. These MOSFETs in an advanced package can be used in a wide range of end applications including desktop personal computers, servers, telecommunications or networking equipment, basestations, and high current industrial systems. "Our customers demand higher current DC/DC power supplies in a smaller footprint to meet the need for increased processing power in the broad infrastructure market," said Steve Anderson, TI's senior vice president and worldwide manager, Power Management. "DualCool NexFET power MOSFETs meet this need by conducting more current in the same form factor." Key features and benefits of DualCool NexFET power MOSFETs: -- Single phase 35-A synchronous buck converter MOSFETs, using single MOSFETs for both the high and low side switches in high-current DC/DC applications. -- Enhanced packaging technology reduces thermal impedance to top of package from 10 degrees to 15 degrees C per watt to 1.2 degrees C per watt, increasing power dissipation capability by up to 80 percent. -- Efficient dual-side heat sinking enables up to 50 percent more current through the FET, giving designers the flexibility to use higher current processors without increasing end equipment size. -- Industry-standard SON package with a 5-mm x 6-mm footprint eases design and keeps cost down, saving 30 mm2 compared to using two standard packages. Availability and pricing DualCool NexFET devices are available in volume now from TI and its authorized distributors. Suggested resale pricing for the CSD16325Q5C is $1.47 in 1,000-unit quantities.
