Lo opuesto de una formulación correcta es una formulación incorrecta. Pero lo opuesto de una verdad profunda puede ser muy bien otra verdad profunda,

| | LTC3525-3.3/-5 : 400mA MicroPower Synchronous Step-up Regulators with
Output Disconnect in an SC70 | | MILPITAS, CA – Linear Technology announces the LTC3525-3.3
and LTC3525-5, 400mA synchronous step-up DC/DC converters with true output disconnect and inrush current limiting in
SC70 packages. They operate from an input voltage range of 1V to 4.5V, making them ideal for single- and multicell
alkaline/NiCd/NiMH, as well as Li-Ion applications. The LTC3525 -3.3 offers a fixed 3.3V output whereas the
LTC3525-5 has a fixed 5V output. The LTC3525-3.3 can deliver up to 140mA of continuous output current from dual AA
alkaline cells. The LTC3525-5 can deliver up to 175mA at 5V from a 3V input. Both devices use synchronous
rectification to enable efficiencies of up to 95%. Their Burst Mode® operation lowers quiescent current to only 7uA,
providing maximum battery run-time in handheld applications. The combination of an SC70 package plus only 3 tiny
externals provides small solution footprints as required in space constrained applications. | | Leer la noticia completa | Miércoles, 19 Octubre, 2005 - 12:19 | |
| LTM4600: 10A DC/DC uModule Provides New Level of Power Density in a
Compact Package | | MILPITAS, CA – A new uModuleTM (micro-module) from Linear Technology
Corporation provides designers a complete 10A switching power supply in a tiny (15mm x 15mm) footprint, low profile
(2.8mm) land grid array (LGA) package. The LTM®4600 is a synchronous switchmode DC/DC step-down regulator with
built-in inductor, supporting power components and compensation circuitry. The LTM4600 is the first in a new family
of uModules from Linear Technology that leverages the company’s core strengths in power management and conversion.
By simplifying power system development, this new high-density power supply reduces development time for a broad
range of systems, including network routers, blade servers, cellular basestations, medical diagnostic equipment,
test instrumentation and RAID systems. | | Leer la noticia completa | Miércoles, 19 Octubre, 2005 - 12:17 | |
| Exar Launches XRT95L53 - EXtendAR 48M™ - The Industry's First
Universal OC-48/STM-16 Multi-protocol Framer | | Fremont, CA, - Exar Corporation today added
EXtendAR 48M™ (XRT95L53) to its product portfolio - the industry's first universal OC-48/STM-16, Quad OC-12/STM-4 &
OC-3/STM-1 multi-protocol framer. This is the first in a family of multi-protocol over SONET/SDH framers extending
Exar's technology leadership into next generation metro core and transport network markets. Deployments of these
highly integrated devices are enabling the convergence of triple-play services together with data over SONET/SDH.
The device employs a unique set of flexible packet framing and encapsulation features combined with optimal SONET
transport capabilities. This makes EXtendAR 48M™ an ideal solution for legacy systems as well as add/drop
multiplexers, Optical Edge Devices (OED's), multi-service provisioning platforms and edge router applications. | | Leer la noticia completa | Miércoles, 19 Octubre, 2005 - 12:10 | |

| Freescale and Flextronics Software Systems demonstrate "OEM-ready" VPN
security application | | MUNICH, Germany — Freescale Semiconductor and Flextronics Software
Systems (FSS), formerly Hughes Software Systems, have collaborated to develop a robust enterprise security router
solution. This advanced IPSec-VPN-based router solution is powered by Freescale's MPC8555E PowerQUICC™ III
integrated communications processor and FSS's Enhanced Security System (ESS) software. FSS, a global end-to-end
communication solutions provider, is providing the first public demonstration of this router platform solution at
the Freescale Technology Forum today in Munich. | | Leer la noticia completa | Miércoles, 19 Octubre, 2005 - 11:52 | |
