In cooperation with the motor vehicle industry, EPCOS (Munich, Germany) has developed the B41684 and B41784 Series of aluminum electrolytic capacitors for onboard electronics, especially in commercial vehicles. In contrast with conventional axial or radial-lead designs, the cathode consists of two collars, one at either end of the can. These form a common conductive surface […]
Maxim Integrated Products (Sunnyvale, CA) has introduced the MAX6381 through MAX6390 microprocessor µP supervisory circuits. Designed to monitor supply rails of 1.8V to 5V in µP and digital systems, these SC70 devices consume 3µA, making them suitable for portable applications. Whenever a monitored voltage falls below the reset threshold, the reset output asserts and remains […]
Agilent Technologies Inc. (Palo Alto, CA) has introduced a high-current device power supply (DPS) that the company claims will expand the processor testing capabilities of its Agilent 93000 SOC Series Test System, while improving yield via high throughput and better speed binning. Rated at 100A and supporting ganging up to 200A, Agilent's new high-current DPS […]
Sipex Corp. (Billerica, MA) reports developing a new synchronous buck controller, the SP6120. This new device is a fixed-frequency, voltage-mode, synchronous, PWM controller. Features include one percent reference, 100 percent frequency accuracy, 40mV over-current detection, 950uA quiescent current, and 10uA sleep current; all these are specified over the full range of input voltage and operating […]
Elantec Semiconductor Inc. (Milpitas, CA) introduced two new 4A single-chip synchronous buck dc/dc converters with integrated power transistors (FETs). The EL7563C and the EL7564C were designed for applications in the communications, graphics, and PC markets that require high-density, small form factor ASIC logic boards, lower operating voltages, smaller PCB space, and higher efficiency power supply […]
Elna Co. Ltd. (Yokohama, Japan) has developed a new, coin-type electrical double-layer capacitor, called DSK609, with a rated voltage of 3.3V and a capacitance of 0.07F. Elna claims that the DSK609, which is 6.8mm in diameter and 0.9mm thick, is able to maintain a high performance level after numerous charges and discharges, and that it […]
Interpoint (Redmond, WA) has introduced a new family of dc/dc converters, the MSS Series, featuring a built-in EMI filter which meets the requirements of MIL-STD-461E and CE102, no external components required. The MSS Series' 125W converters measure 4.6" x 2.4" x 0.45". It was designed to replace the industry-standard configuration of three separate modules — […]
Power Measurement (British Columbia, Canada) has introduced two new features for its ION Series energy and power quality meters: Meter M@il e-mail messaging and WebMeter web-browser support. With MeterM@il, the company's 7500 ION and 7600 ION power meters can now automatically send high-priority alarm notifications or scheduled system-status updates as e-mail messages to anyone, anywhere […]
Interpoint Corp. (Redmond, WA) announces the MSM Series of dc/dc converters delivering up to 5W from a 28V input in a surface-mountable package. Interpoint claims that the new converters have reliable power operation over the full military temperature range of -55 degrees C to 125 degrees C. The MSM Series uses commercially-available discrete components, printed […]
Kollmorgen (Radford, VA) has expanded its DDL line to include the IL03 model and ICD Series. The ICD motor series is a reduced-envelope ironcore motor that features a low attractive force, anti-cogging design in a reduced envelope. It is suited to bridge the gap between the larger IL models and smaller IC coils. According to […]
California Micro Devices Corp. (CAMD, Milpitas, CA) has announced the availability of its CMPWR160 integrated circuit (IC) which is designed to provide an integrated power management solution targeting Universal Serial Bus (USB) peripherals and other hot insertion equipment. The CMPWR160 combines an LDO with a power-on-reset pulse generator. To meet the specification requirements of both […]
Power-One Inc. (Camarillo, CA) has added the HPF3E8E8E7YB to its High Power Series. This modular power supply provides 28V at 68A. With...
Maxim Integrated Products (Sunnyvale, CA) recently introduced the MAX1773 IC that serves as the control logic for a system with multiple power...
General Semiconductor Inc. (Melville, NY) has expanded its Schottky rectifier product line. The company now offers Schottky products with reverse voltages up...
ON Semiconductor Corp. (Phoenix, AZ) has released a dc/dc converter it claims is 60 percent smaller in package size as compared to ON Semi’s previous offering, the MC33466. The NCP1400 is aimed at battery-powered consumer products such as handheld games, cellular phones and digital cameras. Because it is a micropower pulse width modulator (MPWM) step-up […]
