Regulator shuts down to 3.5 μA quiescent current LTC3624 is a high efficiency, 17V input capable synchronous buck regulator that delivers up to 2A of continuous output current to outputs as low as 0.6V. Synchronous rectification delivers efficiencies as high as 95% while Burst Mode operation requires only 3.5μA of no load quiescent current. The LTC3624 switches at a fixed 1MHz frequency, whereas the LTC3624-2 switches at 2.25MHz. Their constant frequency, current-mode architecture minimises switching noise while offering very fast line and load transient response. The LTC3624/-2 operates from an input voltage range of 2.7V to 17V, making it ideal for single cell or multi- cell Li-Ion stack inputs as well as 12V intermediate bus-powered systems. The combination of its 3x3mm DFN package, high switching frequency and tiny, low cost capacitors and inductors ensures a highly compact solution footprint. The LTC3624/-2’s 60ns minimum on-time enables it to step-down 16V inputs to 2.5V with a 2.25 MHz switching frequency (LTC3624-2) without pulse skipping, minimising the size of external components thus offering a very compact, high efficiency 2A step-down solution. Its 3.5μA quiescent current suits it for always-on applications demanding maximum battery run time. For applications requiring the lowest possible noise, the LTC3624/-2 can be configured to run in pulseskipping or forced continuous mode, reducing noise and potential RF interference. Additional features include a power good voltage monitor, internal compensation and thermal protection. The LTC3624EDD and LTC3624EDD-2 are available in a 3x3 mm DFN-8 package, priced at $2.95 (1,000). Industrial grade versions, the LTC3624IDD and the LTC3624IDD-2 are guaranteed to operate over the -40°C to 125°C operating junction temperature range, priced at $3.25. Linear Technology www.linear.com/product/LTC3624 GUI development editor enables better GUIs Altia is a user interface development software company that provides tools for the creation of graphical user interfaces for embedded devices, with users in automotive, medical, industrial, fitness, and home appliance industries. The latest release, Altia Design 11.1, is the centerpiece of Altia’s user interface development tool suite. With the new features rolled into Altia Design 11.1, users are equipped to develop better GUIs than ever before – with exciting new content. Altia offers a GUI editor and graphics code generator that enable development teams to build completely custom user interface models with graphics created from scratch or imported from industry-standard design programs such as Adobe Photoshop. The Altia GUI can be connected to a variety of simulation tools or C code to create a complex, user-driven model which can be shared with users and management teams for testing and validation prior to production. Once approved, Altia’s code generator automatically generates pure C source code that is optimised to take full advantage of the resources of the selected production hardware. New features in Altia Design 11.1 help users deliver extremely high quality GUIs. The Validator gives users the capability to perform real-time validation of their GUI design against general guidelines or even design rules specific to their selected embedded target. Users can now look “under the hood” while their GUI runs within Altia Design to review and trap animation activity with the new Debugger. With Altia Design 11.1, users also can import and control eye-catching 3D mesh files and animations from 3D authoring tools such as Maya and 3DS Max with the all new 3D Scene Object. The new Multi-Plot Object offers cool and custom complex plotting, strip-charting and data logging capabilities for advanced applications. Altia www.altia.com Android digital signage integrates BLE iBeacons Noxel has integrated iBeacons and Android in a unique and powerful digital signage system. The Noxel Xtream A700 player includes an embedded iBeacon, a Bluetooth Low Energy (BLE) module that can be used by retailers and brand marketers for indoor positioning and location-specific push messaging to smartphones. The A700 cliams to be the most powerful Android-based digital signage player on the market, with a Quad Core ARM-A9 processor, embedded 3D Mali 400 GPU, built-in WiFi and available expansion storage. Fast computing and embedded graphics processing ensure digital signage content creators can drive networked screens with HD quality video and smooth motion graphics messages. The A700 is the latest player running on top of Noxel’s Xtream cloud digital signage content management system. The company’s browser-based Software as a Service platform removes the complexity from digital signage operations, allowing users to simply select from a range of Android players, create a Noxel user account and activate the signage service. “Putting an iBeacon on what’s probably the most powerful Android digital signage player available and then managing that in the cloud is what I think sophisticated network operators are now looking for,” said Farbod Sadeghian, CEO of Noxel. “Using Android gives our customers a very cost-effective, stable and rapidly evolving platform” added Sadeghian.” Integrating BLE means the messaging delivered on Xtream-powered screens can also be targeted down to the shopper smartphones and also provide intelligence on consumer behavior.” Noxel has in-house creative and technical teams to develop mobile applications that can use iBeacons for advertising and location mapping.
