National Semiconductor Corp. a présenté aujourd'hui les premiers contrôleurs PWM (modulation de largeur d'impulsions) du marché intégrant leurs quatre drivers de MOSFET de pont aux primaires. Les LM5045 et LM5046 sont bien adaptés pour fournir un rendement et une densité de puissance supérieurs dans les modules quart de brique ou huitième de brique utilisés dans certains applications d'infrastructure de transmissions haute tension.

A new ultra-high-speed operational amplifier (op amp) from National Semiconductor Corp. (NYSE: NSM) delivers the industry’s lowest noise (0.69 nV/sqrt Hz) with -3 dB bandwidth of 900 MHz at a gain of 10. The PowerWise® LMH6629 provides designers a unique mix of wide bandwidth, high gain and precision amplification for systems where minimal noise addition is a key performance requirement. These include 16-bit systems for communications, test an...

The new XC9242/43 series from Torex is a group of synchronous step-down DC/DC converters that can be used with ceramic capacitors and integrates one P-channel and one N-channel MOS power transistors. The small on-resistance of these power transistors permits to obtain high efficiencies for output currents up to 2A. The XC9242/43 operates with input voltages VIN ranging between 2.7V and 6.0V, and its output voltage can be set between 0.9V and VIN ...

The AL8400 linear LED driver controller from Diodes Incorporated has been designed to tightly regulate a wide variation of high brightness LED currents via an external transistor. Suiting a broad range of LED chains in illumination, indication or signage systems, the controller can directly operate from 2.2V to 18V and will drive either N-channel MOSFET or NPN Bipolar transistors.

Maxim's new LNA, the MAX2180, integrates an AGC circuit to optimize car antenna reception while reducing solution size and cost.

Maxim Integrated Products Inc introduit les MAX2769B et MAX2670, des solutions de réception de nouvelle génération haute performance, spécifiquement conçues pour les applications de systèmes globaux de navigation par satellite (GNSS). Ces circuits particulièrement flexibles fonctionnent avec les standards de navigation GPS, GLONASS, Galileo et Compass, et ont obtenu la certification PPAP et AEC-Q100.

Maxim has introduced the MAX1385/MAX1386/MAX11008 dual RF LDMOS bias controllers. At 7mm x 7mm, these highly integrated devices are said to be the industry's smallest LDMOS bias controllers to integrate all of the A/D and D/A interfaces and logic functions required for cellular base-station control. The MAX1385/MAX1386/MAX11008 are uniquely suited to bias the power-amplifier power transistors employed in CDMA, GSM, EDGE, and UMTS cellular base-st...

Cree announced plans to demonstrate a variety of new GaN HEMT RF packaged amplifier and switch products at the IEEE MTT-S International Microwave Symposium (Booth #836) to be held in the Anaheim Convention Center May 25 through May 27, 2010. The products to be demonstrated include a SPDT MMIC switch (300 MHz to 3 GHz); a 25 W MMIC power amplifier (10 MHz to 6 GHz); a 75 W MMIC power amplifier (2.7 to 3.5 GHz); and a 240 W transistor (2.9 to 3.5 G...

ZMDI AG, a global supplier of analog and mixed-signal solutions for automotive, industrial, and medical applications, today announced its entry into the LED market with the first three energy-efficient LED driver ICs of a new family. The drivers achieve up to 95% efficiency and demonstrate ZMDI’s commitment to green technology.

NXP Semiconductors today announced the launch of the first eight products from its new 4th generation low VCEsat (BISS) transistors. The product family comes in two optimized branches – an ultra-low VCEsat and a high-speed switching branch. They are available in a voltage range from 20 V to 60 V and are housed in small SMD packages SOT23 (2.9 x 1.3 x 1 mm) and SOT457 (2.9 x 1.5 x 1 mm).
