    Powering the Intel® Arria 10 GX FPGA with a PMBus Multiphase Buck DC/DC Converter

    Field-programmable gate arrays (FPGAs) are increasingly complex system-on-chips (SoCs) that include not just programmable logic gates and random access memory (RAM) but also analog-to-digital converters (ADCs); digital-to-analog converters (DACs); and programmable analog features and signal-conditioning circuits that enable high-performance digital...

    The road to today’s digital cockpit

    In my first car, there was only an AM/FM radio to keep me entertained as I relied on my own memory to get me from point A to point B. The instrument cluster was traditional, with only needles to estimate if I was driving at the speed limit or if I had enough gas for whatever small journey planned that day. Fast forward to today our lifestyles have...

    For efficiencies’ sake – how to integrate bidirectional power flow into your UPS design (part 1)

    With a growing emphasis on more compact, smaller and more efficient power systems, there is increasing interest in bidirectional converters. A bidirectional DC/DC converter, capable of bidirectional power flow, can combine the two DC/DC converters traditionally required for battery charging and backup operations into one. This brings down the cost,...

    What are the building blocks of high-definition audio systems?

    Audio system designers, responding to customer demand for top audio quality, are looking into high-resolution (hi-res) or high-definition (HD) audio as more and more mid-tier system buyers demand the type of HD audio performance that was previously available only in high-end systems. In the past, a 44.1kHz CD-quality sampling frequency may have been...

    Power Tips: How to upgrade a legacy power bank to USB Type-C™

    With more and more portal devices adopting the USB Type-C™ connector , designing a power bank capable of charging these devices is suddenly a big deal. Unfortunately, the USB Type-C connector is a totally new type of USB connector. Understanding the differences between a USB Type-C power bank from legacy USB power banks is critical for successful...

    Making industrial communication easy with AMIC110 SoCs

    Industrial Ethernet protocols are an important part of factory automation. Today, there are many protocol standards including EtherCAT, Profinet, Powerlink, Ethernet/Industrial Protocol (IP) and Sercos III. Having so many different protocols makes it challenging to develop solutions that can work for several different networks. One solution is to have...

    Do you have the correct PFC to meet the new standard of harmonic current emissions standards?

    International Electrotechnical Commission (IEC) 61000-3-2: 2014 is a new standard of electromagnetic compatibility (EMC) that supersedes IEC 61000-3-2: 2006 and will be enforced as of June 30, 2017. This part of the standard deals with the limitation of harmonic currents injected into the public supply system. It specifies limits for harmonic components...

    System trade-offs for high- and low-side current measurements

    Measuring current may sound like a simple task, but it is not as easy as it sounds. Current can’t be sensed directly; however, it is related to other measureable parameters that you can sense directly, such as voltage and magnetic field density. In general, there are two ways to measure current. The first is by measuring the magnetic field...

    Making a smarter door lock with the SimpleLink™ MSP432™ microcontroller

    Adding an electronic door lock to your front door can provide many features and benefits. For example: Opening the door with a keypad could be very convenient if you are inadvertently locked outside. You can forego bringing your keys when going out for a run. You can give access to others, either temporarily or with time limits and restrictions...

    How to approach a power supply design – part 2

    In the first installment of this two-part series, I described how important it is to have a good specification for properly designing a power supply. In part 2, I will outline which parameters of your specification (see Figure 1) influence the decision for certain topologies. Figure 1: Parameters of your specification, which can influence the...

    Good pin practices with buck converters

    Many synchronous buck converter designers face a common issue: how best to connect the open drain power-good flag, also known as the power-good (PGOOD) pin. In this post, I will explore the expected behavior of power good when it is tied to various different pull-up sources. There has been some misinformation floating around that hopefully this post...
