Atmel today announced that Xirgo Technologies, LLC has selected Atmel's Cortex-M3-based product family for its next-generation enhanced-battery-life asset tracking platform. Xirgo Technologies' existing machine-to-machine communications devices are used by leading companies in automotive insurance, fleet tracking, vehicle financing, and dealer lot inventory verticals. Xirgo is targeting its next-generation platform, designed to address the long b...

NXP Semiconductors has unveiled a suite of new power management solutions that will reduce power consumption in desktop PCs and laptops for the mass market. The highly efficient GreenChip PFC, GreenChip SR controllers and a portfolio of 30V power MOSFETs in LFPAK will be showcased at the Applied Power Electronics Conference (APEC) in Washington in February.

SP Devices today introduced its second evaluation module (EVM) with Texas Instruments (TI). This new EVM combines TI's fastest 12-bit analog-to-digital converters (ADCs) in an interleaved fashion with a Xilinx Virtex-5 FPGA to create the best-performing high-speed digitizer solution in the market. The FPGA comes pre-installed with SP Devices' proprietary time-interleaving technology to eliminate interleaving spurs, which enhances performance and ...

Maxim has introduced the DS4432 low-cost, dual-channel, sink/source current DAC. This I2C-controlled, 7-bit current DAC features two output channels that are explicitly designed for power-supply margin testing and adjustment. Each output channel provides fine control of a DC-DC power supply by sinking or sourcing current directly into the power supply's feedback node.

Maxim has introduced the DS4426, a low-cost, quad sink/source current DAC with tracking control. This device is an I2C-controlled, 7-bit current DAC with four output channels explicitly designed for power-supply margining and adjustment functions. Three of the DAC channels have additional circuitry to provide power-supply sequencing or tracking. Each output channel provides control of a DC-DC power supply by sinking or sourcing current directly i...

Maxim has introduced the MAX15026, a low-cost, DC-DC synchronous step-down controller capable of driving external MOSFETs to deliver up to 25A of output current. This device operates over a wide, 4.5V to 28V input range, and it integrates a ±1% accurate voltage reference to provide an accurate output voltage from 0.6V to 85% of the input voltage.

Maxim introduced the MAX8900A/MAX8900B switch-mode DC-DC chargers with JEITA-compliant battery-temperature monitoring for safely charging 1-cell lithium-ion (Li+) or lithium-polymer (Li-Poly) batteries. These are the first chargers to integrate ±20V overvoltage protection, which allows them to provide added safety and reliability without external switches.

Micrel has introduced the MIC2605/6, two boost regulators operating at 1.2MHz (MIC2605) and 2MHz (MIC2606). Both devices supply up to 0.5A switch current. The devices, which complement Micrel's recently introduced MIC2601/2 family, are aimed at TV-tuners, broadband communications, TFT-LCD bias supplies, positive output regulators, SEPIC converters, DSL applications and local boost regulators. The ICs are currently available in volume quantitie...

ROHM has recently announced the industry’s first mass production of SiC power modules (1200V/100A rated) comprised entirely of SiC power elements as custom module. Incorporating SiC inverters and converters for power conversion in industrial equipment provides a number of advantages over typical silicon-based IGBT modules such as switching loss reduction by 85%, approximately 50% less volume compared to conventional 400A-class Si IGBT modules a...

ZMD AG today announced two high-performance devices to complement its family of LED driver integrated circuits. The ZLED7020 and the ZLED7030 LED driver ICs operate at up to 98% efficiency, thus helping to achieve the highest possible lumen-per-watt output in high brightness LED applications.
