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
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
