Torex Semiconductor introduced the XD9242/43 series, a synchronous PWM step-down DC/DC converter with an integral 0.11W (typ.) P-channel and a synchronous 0.12W (typ.) N-channel switching transistor built-in. Output currents of up to 2A can be achieved using a simple circuit. 

The XD9242/43 operates with input voltages ranging between 2.7V and 6.0V, and its output voltage can be set between 0.9V and VIN by using two external resistors. With switching frequencies of 1.2MHz or 2.4MHz, small inductors can be used, making the series ideally suited to applications where height and PCB area is limited.

The XD9242/43 series features various protection circuits, such as a thermal shutdown circuit that stops operation when the chip's temperature reaches 150°C and a UVLO circuit that does the same when the input voltage decreases below 2.5V. Both of the above functions are implemented using hysteresis, and will allow the XC9242 to resume normal operation when the chip's temperature drops below 130°C and when the input voltage increases to 2.68V respectively. 

Infolytica Corporation today released a new version of their industry-leading MotorSolve software. The motor results in MotorSolve BLDC version 6 can be extended with a new generator analysis solver. This set of loads, parameters and results are for both AC generators and motors operating in generating mode. Any electrical machine template in the BLDC module can be simulated in motor mode or generator mode, depending on the operating condition.

An optimal generator design will be different to an optimal motor design. Most software tools use the fact that motors can act as generators and address only motors. MotorSolve v6 addresses the need for a specialized generator design tool. Using MotorSolve version 6, AC generators and motors operating in generating mode can be properly simulated and analyzed. There are five common load types available: diode rectifier, no load or open circuit, short-circuit, passive impedance loads and infinite bus.

DuPont Electronic Materials announced the launch of a new portfolio of thermal solutions under the brand DuPont Temprion thermal management materials. The portfolio is completely non-silicone and currently includes thermal greases, thermal gap fillers, electrically insulating films and adhesive thermal tapes.  In applications such as hand-held devices, computers, car batteries and high-power electronic motors where heat dissipation is a major concern, Temprion can improve performance, reduce the risk of failure and allow engineers to design with confidence.

Thermal management materials play a critical role in ensuring electronic devices and electrical assemblies run properly.  If heat is not properly dissipated, it can result in catastrophic failure, including fire.  The Temprion portfolio of products offer excellent thermal conductivity, lower thermal resistance, greater heat dissipation and improved thermal stability during continuous use.  

Absopulse Electronics' CTP-300R-F7 Series is the latest addition to its line of 3-phase sine wave inverters designed for railway applications. The 300VA units meet the stringent requirements of EN50155 for electronic equipment used on rolling stock. They deliver a 3-phase output of 208Vrms, line-to-line, at 60 or 400Hz. A 115Vrms phase-to-neutral output can also be used. The inverters operate from wide EN50155 input ranges of 24Vdc (17-34V), 36Vdc (25-51V), 48Vdc (33-67V), 72Vdc (50-101V), 96Vdc (67-135V) or 110Vdc (77-154V). 

Custom input/output options are available on request. A specially designed 3-phase controller module contributes to the reliable operation of the unit. With new design topology and the use of microprocessor controlled high frequency PWM technology, the low profile units are more compact than previous 300VA versions and measure just 254 x 67 x 351 mm. 

AVX Corporation has extended its J-CAP Series conductive polymer capacitors with conductive polymer electrodes, which already delivered the highest energy per volume (Joules/cc) of any SMT capacitor available on the market.

Now available in a large 7361-15 case with a low 1.5mm height profile, and capable of delivering up to an industry-leading 38.8mJ in low-profile SMD designs, J-CAP Series capacitors each feature a conductive polymer electrode that exhibits a benign failure mode under recommended use conditions, and undertab terminations that enable high both volumetric efficiency in small, low-profile case sizes and close positioning for efficient, high-density PCB layouts.

These attributes, combined with the series' high energy, low ESR (50-300mW at 100kHz), and low DCL (0.1CV), allow J-CAP capacitors to deliver compact and cost effective high-energy solutions ideal for backup power applications in demanding solid-state drives (SSDs)- including multilevel cells (MLCs), single-level cells (SLCs), enterprise flash drives (EFDs), and PCI Express (PCIe) drives - in addition to battery-powered portable equipment, industrial alarms, smart power meters, and other mobile devices.

Linear Technology introduced the LTM2893 and LTM2895, SPI (serial peripheral interface) µModule isolators, optimized for Linear Technology’s extensive family of high performance data converters. The LTM2893 and LTM2895 support SPI clock speeds up to 100MHz, more than doubling the effective 40MHz limit of existing digital isolators and enabling the use of higher resolution and higher speed data converters while maintaining zero latency operation. With a fast SPI interface, 6,000VRMS of galvanic isolation, and additional high speed control signals, the LTM2893 and LTM2895 require no external components and provide a simple µModule solution for isolated data converter communications.

The LTM2893 (read only) and LTM2893-1 (read/write) are designed to isolate Linear Technology’s general purpose successive approximation register (SAR) analog-to-digital converters (ADCs), including the LTC2378 family of 20-, 18- and 16-bit 1Msps SAR ADCs or the LTC2348 family of octal, 18- and 16-bit 200ksps/channel simultaneous sampling SAR ADCs. Additional high speed control signals provide support for parallel or chain-connected configurations, as well as analog multiplexers or programmable gain amplifiers. Configurable word length allows SPI access to be tailored to a specific ADC to maximize throughput. With only 30psRMS of additive jitter from input to output, the LTM2893 and LTM2893-1 minimize signal-to-noise ratio (SNR) degradation in ADCs due to jitter. 

TDK Corporation presents the first aluminum electrolytic capacitors that are specified for 60 g in accordance with IEC 60068-2-6. The new generation offers the highest vibration strength and the best electrical performance in a single component. The robust EPCOS capacitors are available in three terminal designs (axial-lead, soldering star und double plated) with dimensions of 16 mm x 25 mm to 18 mm x 39 mm (d x l). They cover capacitance values of between 270 µF and 5800 µF and the voltage range from 25 V to 100 V. In addition, all 60 g types feature a high maximum operating temperature of up to 150 °C and are qualified to AEC-Q200.

TDK uses the axial design to achieve maximum vibration strength. Axial capacitors have crucial design-related benefits over the frequently used single-ended design: Flexible connecting tabs between the welding points and the foils prevent direct transmission of vibrations to the terminals. In addition, the winding is firmly clamped by the can by means of both axial and radial fixation forces. The winding is fixed in the radial direction by means of a ring-shaped compression corrugation in the middle of the aluminum can. 

Keysight Technologies announced the availability of a battery-drain analysis solution that delivers insight into critical applications for the energy, automotive and medical device industries. Keysight is the only company that offers this integrated solution for accurate battery-drain analysis and provides the needed testing information required to manage the wide dynamic-current-range utilized by these devices.

A multitude of mobile, highly dispersed, battery-powered devices exist in energy, automotive and medical environment. Often times their power consumption is growing faster than their capabilities, which  results in battery run-time as the critical point in the operational life of a device.

Medical device manufacturers need to maximize battery life on monitors and sensors that interact directly with the human body and its functions. Energy companies often locate battery-powered devices remotely to collect information from water, gas and electric meters. Automotive engineers must confirm that on-board monitoring equipment will function without failing to ensure safety over many years.
