High efficiency power supplies reduce parts count by 80% in automotive applications Rohm has announced the development of compact, high efficiency Power Supplies designed to drive DDR memory, microcontrollers, and other components in car applications. The BD905xx series integrates a phase compensation circuit and feedback resistor, reducing the number of external parts considerably compared with conventional Power Supply ICs. This simplifies design load and contributes to end-product miniaturization. These Power Supplies use synchronous rectification for high efficiency operation, in combination with Light Load Mode, ensuring superior performance with low current consumption under all load conditions. The chips come in a HTSOP-J8 package, reducing volume by approximately 80% compared with conventional products, claims the manufacturer. Loss is a 10th the level of conventional LDO regulators, resulting in minimal heat generation. This simplifies thermal countermeasures, making it suitable for Microcontrollers and DDR memory used in today’s vehicles that require greater current consumption. Synchronous rectification, coupled with Light Load Mode, results in over 90% efficiency under all load conditions for minimal current consumption. Rohm offers models in different output voltages and currents designed for various automotive systems (1.2V for Microcontroller cores, 1.5V and 1.8V for DDR memory). ROHM Semiconductor Industrial 3D-sensor supports shape scanning and 3D data records The EyeVision image processing software by EVT now also supports the new 3D-sensor EyeScan VR 3D. The sensor based on digital stripe light projection, that supplies readycalculated 3D data records for industrial image processing, is also equipped with the complete command set of the EyeVision software and the newly developed 3D-commands. Stripe projection, image recording and generation of the point cloud are performed in an integrated manner based on an intelligent camera. The projector from Texas Instruments and the ca-mera are synchronized with a frequency of 60 Hz. The EyeScan VR 3D outputs the recorded 3D data directly as a point cloud or a grayscale-coded range map to the evaluation computer and can be integrated in industrial installations via the Industrial Ethernet interface. Commands applications such as Bin-Picking, 3D-Matching and robot guidance can be programmed easily. The EyeScan VR 3D features a robust metal housing with IP65 protection, screw-type standard industrial connectors, a 24V connection, an Ethernet Interface as well as hardware and software triggers. Eye Vision Technology www.evt-web.com Data acquisition tool for Linux supports digitizer, www.rohm.com/eu waveform generator and digital I/O cards The sixth generation of the SBench 6 Data Acquisition software from Strategic Test is available for both Windows or Linux users. SBench continues to support all of the companies PCI Express, Automotive hub controller ICs now in 7x7x1.0mm 48-pin QFN package Seiko Epson has begun shipping a new addition to its S2R72A4 series USB hub controller ICs for automotive applications. The series, which is engineered to operate in a temperature range from -40 to 105ºC, now includes a 48-pin QFN package measuring only 7x7x1.0mm. The convenience of USB ports is making them a popular choice for automotive equipment such as car navigation systems. Epson’s USB hub controllers for automotive applications meet the rigorous quality required by the automotive industry and support stable communications even with long USB cables. The chip has one upstream port and four downstream ports (2 High-Speed ports and 2 full-speed ports). The upstream port is locked in USB full-speed mode and can be used as a USB full-speed hub (USB High-Speed nonsupported hub). It can also be locked into USB full-speed even if the destination host supports USB high-speed, which is effective in improving EMI/EMC performance and reducing power consumption. The device operates from LVDD: 1.8 V (internal) HVDD: 3.3 V (USB unit). Epson Europe Electronics www.epson-electronics.de PCI, PXI and CompactPCI digitizer, waveform generator and High-Speed digital I/O cards, some 300 variants in total. The Base version of Sbench 6 is supplied at nocost with each UltraFast card. In addition, a fully functional demo version of the Professional Version with a limited run time is also included. The software is also able to run simulated demo cards to allow full software test even without hardware. For applications that require more features, the SBench 6 Professional version is available for 1190 Euro. Key features of the Professional version include fast Data Acquisition supporting RAID disk arrays, with the capability to acquire and handle GBytes of data. The tool can display analog data, digital data and frequency spectrum. It has integrated analysis functions, an import and export filter, enhanced cursor functions, state-ofthe art drag-and-drop technology and a thread-based program structure. The software is able to measure in Oscilloscope mode as well as long time transient recording mode (streaming mode). A special feature of SBench 6 is the segmented view that allows display of segment based signals together with signals of a second timebase (ABA mode) as well as highly precise timestamps. Besides this SBench 6 data can be exported into ASCII, Wave and MATLAB.
