Power switches are tailored for DC/DC
duties
100, 200 and 220V N-channel UltraFET devices come in ultracompact moulded leadless packages.
Expanding its broad portfolio of power switch solutions, Fairchild Semiconductor has unveiled new 100, 200 and 220V N-channel UltraFET devices available in ultracompact (3 x 3mm) moulded leadless packages (MLPs) These devices are ideal for primary-side switches in isolated DC/DC convertor applications, such as work stations, telecom and networking equipment, where improving system efficiency and saving board space are mandatory design goals

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Fairchild's 200V device, the FDMC2610, boasts the industry's lowest Miller charge (3.6 versus 4nC) and the lowest on-resistance (200 versus 240mohm) when compared with similar 200V MLP 3x3 devices on the market.
These characteristics result in a 27% better figure of merit and translate into superior thermal and switching performance in DC/DC convertor applications.
The 200V device also offers best-in-class thermal resistance (theta JC) compared with similarly packaged devices (3 versus 25C/W), a heat-dissipating feature that ensures reliability even in demanding environments.
"Fairchild now offers designers ultracompact 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 convertor applications".
In addition to offering superior thermal and switching performance over similarly packaged MLP devices on the market, Fairchild's UltraFET devices consume 50% less board space than SO-8-packaged devices typically used in DC/DC convertor designs.
This package-size reduction enables engineers to design smaller, higher-density DC/DC convertors 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.
