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
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.
First Digitally Controlled Microphone Preamplifier? Product News 12/24/2003 Post a comment TI introduced the industry's first digitally controlled microphone preamplifier IC. The PGA2500 is designed for use as a front end for high-performance analog-to-digital converters in a variety of professional audio applications, such as microphone preamplifiers, digital audio mixers and recorders, and broadcast and studio equipment.
Active-clamp PWM controllers tweak switchmode supplies Product News 12/19/2003 Post a comment Texas Instruments' newest generation of pulse-width modulation (PWM) controllers, the UCC2891 through UCC2894, are designed to significantly simplify implementation of active clamp/reset and synchronous rectifier topologies for high-efficiency switching power supplies. The peak current-mode controllers increase efficiency in off-line power supplies and DC/DC converters used in high-end desktops, servers, 48-volt telecommunications, data communications and 42-volt automotive systems.
STMicroelectronics' embedded Dual-Mac DSP core tops 600 MHz Product News 12/19/2003 Post a comment STMicroelectronics is targeting the new generation mobile terminals, cellular infrastructure equipment, networking, broadband modems, voice-over-IP, data storage and mobile multimedia for its new embedded dual-MAC DSP core that can run at above 600MHz or that consume less than 0.1mW/MMAC (Million MAC) in a typical portable telecom application.
Secondary-side drivers do more to protect MOSFETs Product News 12/19/2003 Post a comment Linear Technology's LTC3900 and LTC3901 are two secondary-side synchronous N-channel MOSFET drivers designed to go the extra mile to protect the external MOSFETs of a DC/DC converter during normal and light load operation, power up/down, and when the driver supply voltage drops too low. A programmable timeout function disables the synchronous drivers when the synchronization signal between the primary and secondary sides is missing or incorrect. Additionally, the ICs turn off the MOSFETs if indu
ADI broadens software tools line for DSPs Product News 12/19/2003 Post a comment Analog Devices, Inc. is beefing -up its line of software tools for its DSPs with the launching monday Dec. 22 of USB-based emulators and the VisualDSP++ integrated development and debugging environment (IDDE) release 3.5.
ICs regulate satellite receivers Product News 12/19/2003 Post a comment Allegro MicroSystems' four new low-noise block voltage regulators (LNBRs) are designed for satellite set-top box systems. They provide both power and interface signals to the LNB downconverter via the system's coaxial cable. The new chips provide the flexibility of two-way digital satellite equipment control (DiSEqC) encoding or, optionally, legacy system compatibility (non DiSEqC operation).
Hot Forecast News & Analysis 12/18/2003 Post a comment G. Dan Hutcheson, president of VLSI Research Inc., raised his bullish semiconductor and chip-equipment forecasts for 2004, but he also warned that the overall IC market is overheating.
Looking ahead: Op Amps are hot and getting hotter Product News 12/18/2003 Post a comment What a year it has been for operational amplifiers, those versatile circuits that can be hooked up to your design in hundreds of ways. Several companies have introduced upwards of 50 different op amp products in 2003 with predictions to introduce similar numbers in 2004. In just the 100+ MHz region there were more than 150 new op amp introductions from the suppliers this year.
Going from 8- to 32-bit MCUs Takes Tools Product News 12/17/2003 Post a comment Because the main concern in migrating from an 8-bit microcontroller to a
32-bit device is how to reuse existing software, designers need 32-bit choices
that offer peripheral compatibility with 8-bit MCUs.
