Core regulators power next-generation notebooks Product News 10/10/2005 Post a comment Intersil Corporation's ISL6260B multiphase regulator and ISL6262 two-phase regulator with integrated drivers boast higher efficiency and faster transient response for powering Intel's next generation processing cores for the notebook market.
PWMs facilitate easy, accurate DC/DC conversion Product News 10/7/2005 Post a comment International Rectifier's two new synchronous buck PWM controllers, touting one-percent accuracy for next-generation 12-volt systems, are suited to 15-amp DC/DC point of load (POL) applications for powering dual data rate (DDR) memory, FPGAs, and video graphics processors. Combined with suitable (external) power MOSFETs, these controllers are designed to offer greater design flexibility and improved performance as compared to competing integrated or discrete solutions.
Post amplifier spotlights sensitivity Product News 10/7/2005 Post a comment Micrel Inc. expanded its family of limiting post amplifiers with a 1.25 Gigabit/s device featuring 3.3-V operation with better than 5-mV sensitivity for datacom and telecom digital apps.
Video current D/A converters: some fundamentals for IP use Design How-To 10/5/2005 Post a comment Typical video D/A converters have 8 to 10 bits of accuracy and operate at speeds between 100 to 400 MHz. At these speeds, current D/As are the preferred architecture since current D/As are less sensitive to capacitive loads. However, a method is needed to convert the output currents into voltages. Here are design ideas on how to best accomplish this technique without losing accuracy.
Decoder boasts CPU enhancement Product News 10/5/2005 Post a comment STMicroelectronics Inc. introduced the first MPEG-2 decoder chip in a new family for low-cost set-top boxes and DVD recording, which are said to boost computing power by over five times compared to earlier devices.
Supply chip simplifies OMAP, XScale powering Product News 10/5/2005 Post a comment Texas Instruments' TPS65020 has three step-down regulators for providing the core voltage, peripheral, I/O, and memory rails for OMAP-based mobile handsets and XScale-based multimedia devices. The device, which can be powered by a single lithium-ion or lithium-polymer cell, includes integrated FETs and an I2C communications interface that allows full programmability and dynamic voltage scaling of the core voltage.
Process augments op amp performance Product News 10/3/2005 Post a comment Santa Clara, Calif. National Semiconductor Corp. believes its new VIP50 manufacturing process will raise the bar for bandwidth-to-power ratios found in op amps today with this process resulting in a huge bandwidth boost and 90 percent savings in current consumption.
