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
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
