half-bridge solution - the Ultra FRFET family- optimizes designs by providing
best-in-class reverse recovery time (trr) of 35ns - 65ns and the industry's
smallest reverse recovery current (1.8 - 3.1A). These devices are part of a
comprehensive portfolio of MOSFETs that offer designers a wide range of
breakdown voltages (-500V to 1000V), state-of-the-art packaging and
industry-leading FOM to deliver efficient power management anywhere electronic
power conversion is needed. Fairchild's Ultra FRFET (Ultra Fast recovery
MOSFET) is an industry first. Ultra FRFET works well with less than four diodes
in high voltage backlight inverter and reduces costs in high voltage backlight
inverters by approximately $0.20. Potential savings are expected to be over
$26M in 2010 because the production of CCFL backlit LCD TV is 130M sets. The
combination technology of lifetime control process and UniFETTM mosfets achieves
soft reverse recovery characteristics and big diode dv/dt immunity guaranteeing
20V/ns compared with 4.5V/ns of normal MOSFET. The soft reverse recovery characteristics
improved EMI characteristics in LCD TV sets and big diode dv/dt immunity
improved system reliability during high frequency operation at high
temperatures. When compared to alternate solutions offering a typical gate
charge of only 16nC, the Ultra FRFET products are instrumental in reducing the
turn-on and turn-off losses of the MOSFET through its significantly lower gate
charge (Qg(typ) = 11nC). These products also feature a robust dv/dt immunity of
20V/ns, ensuring reliability and strong EMI performance to protect the LCD TVs
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
