| | Fairchild Semiconductor Establishes Chicago Power Design Center for
Industrial and Consumer Applications | | South Portland, Maine — Fairchild Semiconductor adds
to its growing number of worldwide Global Power Resource™ Design Centers with the addition of the Chicago, Illinois
laboratory. This design center provides expertise in quasi-resonant designs offering less noise, lower EMI and
higher efficiency than hard-switching, fixed-frequency designs in applications such as color TVs and set-top boxes.
Additionally, Fairchild’s quasi-resonant designs offer design engineers the advantage of a highly integrated
solution that combines a MOSFET and controller in one package. Cost-sensitive designs in industrial and consumer
applications can realize a lower overall system cost through a reduction in the amount of filtering as well as heat
sink size and by the reduced number of components. | | Leer la noticia completa | Martes, 26 Julio, 2005 - 05:21 | |
| IBM Successfully Delivers ASC Purple Milestone Demonstration On Time | | ARMONK, NY - IBM today announced that ASC Purple, a system to be dedicated to a critical
national security mission, was demonstrated on time and exceeded performance objectives in a recent milestone test.
IBM plans to deliver the system to LLNL in August, with acceptance testing scheduled for October 2005. LLNL plans
for ASC Purple to be housed in the recently completed Terascale Simulation Facility (TSF). | | Leer la noticia completa | Lunes, 25 Julio, 2005 - 05:29 | |

| | | VERTICAL MOUNT POL CONVERTERS OCCUPY MINIMAL BOARD SPACE AND FEATURE | | FRAMINGHAM, Mass. — Artesyn Technologies launched eight new vertical mount non-isolated
point-of-load dc-dc converters designed specifically for applications where board space is at an absolute premium.
The new PTV series converters are fully compatible with POLA (Point-of-Load Alliance) standards – providing users
with the flexibility and security of multiple sources of supply – and pack latest generation power conversion and
control technology into exceptionally small footprint modules. The smallest model in the series – the PTV03010 – is
a 3.3 Vin, 8 A output unit that takes up a mere 0.3 in2 of PCB real estate. | | Leer la noticia completa | Viernes, 22 Julio, 2005 - 11:11 | |

| NEW SLURRY FROM ROHM AND HAAS ELECTRONIC MATERIALS | | Phoenix, Arizona - Rohm and Haas Electronic Materials, CMP Technologies introduced a new copper barrier
slurry designed specifically to help customers deal with chemical mechanical planarization (CMP) in low-k
integration schemes at the 90nm and 65nm technology nodes. Developed out of close collaborations with device
manufacturers, the new LK393c4 copper barrier slurry’s selectivity and removal rates enable users to achieve a 25 to
30 percent improvement in wafer throughput and cost of ownership over currently available slurry formulations. | | Leer la noticia completa | Viernes, 22 Julio, 2005 - 11:04 | |
