Making the Most Out of 802.3af Design How-To 12/30/2003 Post a comment New power-over-Ethernet specification allows designers to remove the power cord and powerup over Ethernet lines. Here's a look inside this new IEEE spec.
Quad regulator takes care of LCDs Product News 12/30/2003 Post a comment Linear Technology's LT1943 quad output regulator is designed specifically to power and protect 22-inch and larger thin-film transistor liquid-crystal display (TFT LCD) panels. Included in the power block (three supplies for the display as well as a 3.3- or 5-V logic supply) is a 2.6-amp boost regulator to drive the TFTs, a high voltage TFT biasing output, an inverter for negative TFT biasing, and a 2.4-amp buck regulator to power VLOGIC. All of the switchers are synchronized to an internal 1.2 M
Tactile sensors flex to all pressures Product News 12/30/2003 Post a comment Combining a sensor with signal conditioning electronics, Pressure Profile Systems, Inc.'s new C500 tactile sensor can discern the slightest pressure on curved and angular surfaces.
Single Chip Processor for DVD Recorders Product News 12/30/2003 Post a comment Murray Slovick's first take on the DMN-8602 processor for DVD recorders is that LSI Logic has come to play. Of particular note is the company's claim that the chip integrates a number of system functions resulting in a cost reduction (BOM) of up to $20 over and above LSI Logic's previous DVD recorder parts.
Active-clamp PWM controller peaks ZVS designs Product News 12/29/2003 Post a comment National Semiconductor's LM5025 is an active-clamp PWM controller for high-frequency forward converter topologies designed to boost the efficiency and power density of conventional forward regulators. Using the company's analog bipolar-CMOS-DMOS technology to cut external component count, the LM5025 integrates a 3-amp driver, 100-volt start-up bias regulator and a user programmable 1 MHz oscillator, and the chip exhibits a total propagation delay of less than 100 ns, thus suiting it to a variety
DC/DC driver IC addresses pre-biased loads Product News 12/29/2003 Post a comment Intersil's new ISL6608, for driving two n-channel power MOSFETs in synchronous-buck, multiphase power converters, features a diode-emulation mode that eases power-up into a pre-biased load and maximizes performance under light-load conditions.
Eighth-bricks tout high thermal performance Product News 12/29/2003 Post a comment Ault's HDE1-75 single-output eighth-bricks, suited to high-temperature ambient environments, deliver up to 25 amps at 1.8, 2.5, or 3.3 volts from a 36-75 VDC input. Using the company's Tronix-Flex technology, these 75-watt, 350-kHz DC/DC converters feature an FET array design that stacks MOSFETs in parallel on multi-level printed circuit boards and an integrated heat sink to achieve high power density at elevated temperatures (100 watts/in3 at 85°C) despite minimal air flow.
