ELECTRONICS: The LTC3616 is a high efficiency, 4MHz synchronous buck regulator from Linear Technology that incorporates a constant frequency, current mode architecture. Low resistance internal switches allow the LTC3616 to deliver up to 6A of continuous output current from a 3mm x 5mm QFN package and its low dropout operation allows the output voltage to range from 0.6V to just millivolts below VIN. The LTC3616 operates from an input voltage of 2.25 to 5.5V, making it ideal for single-cell Li-Ion applications as well as 3.3 or 5V intermediate bus systems. Its switching frequency is user programmable from 300kHz to 4MHz, enabling the use of tiny, low cost capacitors and inductors.
The LTC3616 uses internal switches with RDS(ON) of only 25mΩ and 35mΩ to deliver efficiencies of up to 95 percent. Burst Mode® operation reduces no-load quiescent current to only 75µA, maximizing both light-load efficiency and run-time in battery-powered applications. An adjustable Burst Mode clamp enables designers to optimize light load efficiency. For applications requiring the lowest possible noise, the LTC3616 can be configured to run in either pulse-skipping or forced continuous modes, reducing noise and potential RF interference. Additionally, programmable switching slew rates can further reduce potential noise concerns. The LTC3616 also offers inputs for tracking capability as well as a DDR memory mode in which the device can source/sink ±3A. Additional features include optional active voltage positioning, a Power Good voltage monitor, external synchronization capability and thermal protection.
The LTC3616EUDD is available in a 3mm x 5mm QFN-2. Pricing starts at $3.80 each in 1,000-piece quantities. An industrial grade version, the LTC3616IUDD, is guaranteed to meet specifications over the -40 to 125C operating junction temperature range and is priced at $4.47 each in 1,000-piece quantities.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
