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
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
