Tyco Electronics Corp.'s (Menlo Park, CA) subsidiary, Raychem, announced its new networking and telecommunications over-current circuit-protection component, the TSL250-080 device. With a 30 percent smaller footprint than existing TS250 devices, the surface-mount PolySwitch resettable fuse is designed for network cards with increased port densities and provides protection against power faults in LANs, wireless local loops, […]
ZANE International Inc. (Grand Junction, CO) recently announced the OEM dc voltage doubler. With a conversion efficiency approaching 99 percent at full-load, zero additional heat sinking is normally required for the approximately 2" square module, according to ZANE. Delivering 100 times the output of a conventional doubler with only 0.1V ripple at full-load, this doubler […]
Fairchild Semiconductor International Inc. (South Portland, ME) stated that its fourth quarter 2000 sales were in the range of $468.0 to $470.0 million. Trade revenues were up 36 percent from fourth quarter 1999, and up slightly from third quarter 2000, while foundry revenues (revenues from manufacturing service agreements with other semiconductor vendors) dropped sequentially. "We […]
Semtech Corp. (Newbury Park, CA) debuted a new power-management device that integrates a dc/dc switching regulator controller and two linear regulators, intended to provide the three distinct voltage levels required in new Pentium III-based systems and other tri-mode power-supply applications. Semtech claims that the new SC1109 device reduces component count, board-space requirements and has a […]
Lambda Electronics (San Diego, CA) is now offering the 1U-sized SC150 Series of 150W ac/dc switching power supplies for telecom, point-of-sale, and test and measurement applications. Lambda claims that this series can be configured to thousands of models, delivering up to four output voltages from 1.8V to 48V. The new units offer active PFC for […]
AVX Corp. (Myrtle Beach, SC) has named John S. Gilbertson the company's new CEO effective July 25, 2001. He will be replacing Benedict P. Rosen, who will remain AVX's chairman.
