productroundup Shunt regulator betters 431 specs, replaces Zeners The AP431i adjustable shunt regulator, introduced by Diodes Incorporated, features a 50 μA minimum cathode current that is significantly lower than equivalent industry standard 431 devices. Manufacturers of switch-mode power supplies can target applications that require very low power dissipation, particularly 12V/19V adaptors/chargers. The AP431i three-terminal adjustable shunt regulator features fast turn-on characteristics, a low temperature coefficient and low output impedance. The AP431i has the same electrical specifications as a standard 431, while having an advantage in being able to regulate with a low minimum cathode current. SmartMSD simplifies USB file transfer SEGGER’s Smart Mass Storage Device (SmartMSD) uses the proven MSD standard to easily stream files to and from USB devices, by Drag and Drop command. The active file system technology employed in SmartMSD is unique. Once the USB device is connected to the host, files can be read or written to the application without the need for dedicated storage memory. The SmartMSD software analyses what operation is performed by the host and passes this to the application layer of the embedded target, which then performs the appropriate action. Complete article, here Debug over USB for system insights in complex SoCs UltraSoC, provider of advanced debugging and analytic technology for embedded systems, has announced USB-based debugging capabilities within its flagship UltraDebug product. This announcement relates to its technology that allows a single high-speed chip interface – in this case USB 2.0 – to be used simultaneously for both system communication and for analytics applications such as debugging. Future developments will support other standard interfaces, such as Ethernet or PCIe. UltraDebug helps engineers to understand the complex interactions between software and hardware in today’s complex chips, which frequently have several billion transistors running tens of thousands of lines of software code. Adding dedicated analytics circuitry to the chip dramatically simplifies the process of debugging – a process which today commonly consumes up to half of the total development time of a large SoC. Complete article, here DLP chipset for automotive head-up display Texas Instruments has introduced a first DLP (Digital Light Processing) chipset for automotive head-up display (HUD) applications. Combining the imaging qualities of DLP technology with automotive reliability, the chipset enables head-up displays with the widest field of view (FOV) available; up to 12 degrees. The chipset gives high brightness, colour and contrast levels and provides manufacturers with a scalable platform. The DLP3000- Q1 chipset consists of a DLP 0.3-inch wide video graphics array (WVGA) digital micromirror device (DMD) and DLPC120 controller.
