    Voltage regulator features – inside the black box

    As I travel and meet with customers across many market sectors, I have come to realize that many hardware designers become power-supply engineers by necessity. Hardware designers are responsible for designing voltage regulators that remain electrically and thermally stable under operating and expected worst-case conditions; meet the required power specifications of processors, application-specific integrated circuits...

    Protect automotive USB circuits against short-to-battery faults – part 1

    Vehicle manufacturers continue to make infotainment systems an extension of the multimedia experience. The USB interface has been a fundamental element of the infotainment architecture, and thus manufacturers have subjected this originally consumer-focused interface to significantly more stringent protection requirements. Among these is the need to protect against shorts to the vehicle battery that can occur during assembly...

    An introduction to the Internet of Things

    By now, it’s common to hear conversations about the Internet of Things (IoT), but why? Why is there so much buzz around the IoT? What is the IoT? The IoT is an enabling technology with the ability to impact nearly everything we do and how we do it. It will allow for decision making on a much larger scale than ever before. Being able to control all of the machines in a factory or all of the street lights in...

    Tapping the cloud for IoT sensing solutions

    The Internet of Things (IoT) is linking people, devices and cloud data storage services at an unprecedented rate. By 2020, some analysts estimate 50 billion digital devices will be connected to the Internet. Customers are leveraging DLP® Products to create new, unique capabilities in remote sensing, including spectroscopy, 3D machine vision and smart home applications. For diverse industrial areas such as pharmaceuticals...

    Thinking beyond the buck controller for high-output power supplies

    Choosing the right buck-converter topology for a battery-connected automotive power supply is usually pretty straightforward. For currents up to ~3.5A, a synchronous buck converter is the best choice. A buck converter with an integrated MOSFET half bridge requires less space on the printed circuit board (PCB), fewer external components and a lower bill-of-materials cost. The synchronous design is good for efficiency and...

    How low can you go? How to reduce power consumption in data-acquisition systems

    When trying to reduce system power consumption, one method is to look for devices to optimize or remove. Another method is to evaluate the system as a whole and optimize for system functionality before evaluating at the component level. In this post,...

    Where should I place my battery’s gas gauge?

    Imagine for a second how useful (or useless) your car would be without a gas gauge. Not very appealing, is it? The same principle applies to battery-powered systems. Including a gas gauge in a battery-powered system provides accurate capacity information and helps extend the runtime of the application. TI provides multiple solutions for single- and multi-cell applications, with gauging algorithms such as Impedance...

    Power Tips: Simple PSRR measurement with a frequency analyzer

    The power supply rejection ratio (PSRR) is the power supply’s ability to reject ripple voltage applied at the input. This is normally done by adding a high-current power amplifier in series with the input source, driving it with a frequency-swept signal from a signal analyzer, and measuring the ratio of V IN to V OUT at each measured frequency. These power amplifiers are expensive, however, and easily damaged during...

    Advantages of wide band gap materials in power electronics – part 1

    With the introduction of new wide-bandgap materials such as gallium nitride (GaN) in transistor fabrication, significant figure-of-merit improvements translate into potential improvements in power supplies. In this two-part series, I’ll discuss how these new wide-bandgap materials can benefit new designs. Using newer materials that exhibit a higher bandgap than silicon-based semiconductors enables a reduction...

    A much smaller boost converter for slightly smaller power banks

    With smartphones and tablets growing in size every year, their battery capacities must also grow. Increasing the battery’s milliamp-hour (mAh) capacity provides the same or increased operating time at its operating power, which also increases with additional functionality and larger display sizes. If charged at the same rate as smaller-capacity batteries, these larger batteries take longer to fully charge. Consumers...

    Improving road safety by the headlight: LED matrix manager

    In my previous blog post , I introduced an automotive light-emitting-diodes (LED) headlight unit using switch-mode regulators. Those LED headlights are static; that is, they either turn on or off. You might turn on the fog lamps when the weather is bad or use your low beams at night and save your high beams when driving uphill. However, have you ever experienced a glare from a vehicle with its high beams turned on (as...
