UltraFET Devices offer thermal resistance.

Press Release Summary:

Housed in 3 x 3 mm, molded leadless packages, N-Channel UltraFET devices come in 100, 200, and 220 V models. They are suited for primary-side switches in isolated dc/dc converter applications, such as workstations, telecom, and networking equipment. Rated at 200 V, Model FDMC2610 features Miller charge of 3.6 nC and on-resistance of 200 mW. All units are Pb-free and meet or exceed requirements of joint IPC/JEDEC standard J-STD-020C.

Original Press Release:

Fairchild Semiconductor's Family of UltraFET Devices in MLP 3x3 Offers Industry-Leading Switching/Thermal Performance for DC/DC Converter Designs

New 200V N-channel device offers best-in-class FOM and thermal resistance

South Portland, Maine--November 9, 2006--Expanding its broad portfolio of power switch solutions, Fairchild Semiconductor (NYSE: FCS) announces new 100V, 200V and 220V N-channel UltraFET devices available in ultra-compact (3mm x 3mm) molded leadless packages (MLP). These devices are ideal for primary-side switches in isolated DC/DC converter applications, such as work stations, telecom and networking equipment, where improving system efficiency and saving board space are mandatory design goals.

Fairchild's 200V device, the FDMC2610, boasts the industry's lowest Miller charge (3.6nC vs. 4nC) and the lowest on-resistance (200mOhms vs. 240mOhms) when compared with similar 200V MLP 3x3 devices on the market. These characteristics result in a 27 percent better Figure of Merit (FOM) and translate into superior thermal and switching performance in DC/DC converter applications. The 200V device also offers best-in-class thermal resistance (Theta JC) compared with similarly packaged devices (3C/W vs. 25C/W), a heat-dissipating feature that ensures reliability even in demanding environments.

"Fairchild now offers designers ultra-compact MLP 3x3 power switches with industry-leading performance," said Mike Speed, Fairchild's market development manager, communications. "We've combined the advantages of our PowerTrench® process and advanced packaging technology to enhance Fairchild's UltraFET portfolio. These products are especially tailored to meet demanding design challenges posed by today's DC/DC converter applications."

In addition to offering superior thermal and switching performance over similarly packaged MLP devices on the market, Fairchild's UltraFET devices consume 50 percent less board space than SO-8-packaged devices typically used in DC/DC converter designs. This package-size reduction enables engineers to design smaller, higher-density DC/DC converters by reducing the MOSFET footprint area and enhancing package thermal capability.

To complement this offering of three N-channel devices, Fairchild also introduces a 150V P-channel planar UltraFET device, which is also available in an MLP 3x3. This device option offers designers a complete solution for their active-clamp switch topologies requiring both N- and P-channel MOSFETs.

These lead (Pb)-free devices meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.
