Power chip drives point-of-load applications News & Analysis 11/25/2003 Post a comment Texas Instruments' TPS54350 is the newest addition to the company's SWIFT (switcher with integrated FET technology) family, a 3-amp, nominal 15-watt DC/DC (non-isolated) PWM buck converter suitable for point-of-load applications. Working from a 4.5- to 20-volt input, the converter is especially useful for powering DSP, FPGA, and microprocessors directly from a mid-voltage bus, versus an additional low-voltage bus.
Security for storage networks is incremental News & Analysis 11/25/2003 Post a comment Most companies routinely assess their data security with overall security policy health checks, site surveys, ethical hacking for penetration testing and reviews of processes, systems, networks and applications.
Analog mux parts claim reduction in signal feed-through News & Analysis 11/25/2003 Post a comment Intersil's new MightMUX devices claim a 99 percent reduction in off-state leakage current and a 99 percent reduction in off-state signal feed-through " at least, compared with Intersil's previous-generation switches. But then, a 2-pA leakage current is respectably low.
Push is on for secure operating systems News & Analysis 11/25/2003 Post a comment The need for a secure operating system is often associated with government projects for the Department of Defense, the National Security Agency (NSA) or other agencies with sensitive information related to national security.
Supervisor IC indicates fan failure News & Analysis 11/25/2003 Post a comment A watchdog timer can monitor the tachometer output of your PC fan, and tell you when you have a problem. From the November issue of Planet Analog magazine, a Maxim apps engineer shows how.
Chips from magnetoresistive material advance in lab News & Analysis 11/25/2003 Post a comment Magnetoresistive materials being developed by researchers at the University of Chicago and Argonne National Laboratory may offer a promising alternative to the semiconductor industry's current chip-making processes. Instead of relying on atomic accuracy, theorists say that the researchers, who have harnessed nanoscale imperfections in a material, could use it as a thin film for chip fabrication. Colin Johnson reports.
Philips, JSMC form power semiconductor joint venture News & Analysis 11/25/2003 Post a comment Dutch electronics giant Royal Philips Electronics NV is forming a joint venture with Jilin Sino-Microelectronics Co. Ltd. (JSMC) to develop, design and manufacture bipolar power semiconductor chips, Philips said Tuesday. Products developed under the joint venture will be marketed and sold by the parent companies, but financial details of the joint venture, dubbed Philips Jilin Semiconductor Co. Ltd. (PJSC), were not been disclosed. From London, Peter Clarke has this report.

Cable assemblies offer design flexibility Product News 11/25/2003 Post a comment Meeting hot-swap and cable I/O applications, the expansion of Tyco Electronics' MULTI-BEAM XL line of modular power/signal connectors offers customers the design flexibility to connect hot-swap power supplies to other components of a power distribution system, without the use of a power distribution board.
Ultra-slim SSR targets industrial and appliance apps Product News 11/25/2003 Post a comment Fujitsu Components America, Inc. offers a new ultra-slim solid-state relay (SSR) for industrial and appliance applications such as PLCs, process controls, remote switching, air conditioners, vending machines and photocopiers. Designed for high-density PC-board mounting, the new FTR-SL is a 1A, SIP-type SSR that measures 5 mm (W) x 28 mm (L) x 15 mm (H). The device is pin-compatible with Fujitsu's existing FTR-LY electromechanical relay.
CMOS transceiver circuit builds a compact RFID reader News & Analysis 11/25/2003 Post a comment EM Microelectronic offers a practical circuit for an RFID card reader. The author offers instructions for configuring the circuit for read-only, read-write and passive transponder applications. Because the operation is dependent on the resonance of the RFID card with its reader, tuning capacitor selection can be critical, he advises.
