    Small and efficient power supply for the Altera™ MAX® 10 FPGA

    Are you designing with Altera’s™ MAX® 10 FPGA? If so, you probably just want a small, efficient and proven power solution without having to devote much thought or design time to it. The power supply should be simple and small enough to fit on a fraction of your printed circuit board (PCB) and efficient enough to not require heat sinks...

    Design competitive USB OTG power supply

    Universal Serial Bus or “USB” has been around for a long time; at the very beginning, USB had exclusive primary and secondary hosts. The primary data transmission was mainly from the PC and the secondary transmission was to mobile phones, mice or keyboards. With the development of consumer electronics, however, the demand for data transmission...

    Design advantage of D-CAP control topology

    Texas Instruments first implemented the D-CAP™ control topology in 2004 on a double-data-rate (DDR) controller, the TPS51116 . TI developed D-CAP technology as a form of current-mode control using the output capacitor equivalent series resistance (ESR) as the sense element. The name “D-CAP” refers to the current information that’s...

    The effects of gate-driver strength in synchronous buck converters

    The peak voltage at phase node, VPH, in a synchronous buck converter is one of the main specifications to determine converter reliability. Designers usually allow phase-node ringing to be as much as 85% to 90% of the MOSFET data sheet’s absolut...

    A handy tool for power-supply designs

    Versatility is a good thing. You probably have one of those tools in your toolbox – probably not advertised as such, but something that just ended up being good for everything from prying and bending, to loosening stuff. You reach for that tool repeatedly because you’re comfortable with it and you know that it’s going to do the job...

    Managing power scaling and sequencing the analog way

    With the emergence of Internet of Things (IOT) applications , more and more application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs) are being deployed into cloud computing and server system applications. These high-performance end applications demand higher processing power and ever-increasing clock speeds. Voltage...

    It's a wrap at APEC – power trends, friends and automobiles

    The 2017 Applied Power Electronics Conference (APEC) did not disappoint. The annual pilgrimage to the premier global event in power electronics was full of ideas, implementations and illuminations. Let me share some of the key takeaways from the energizing week. Data center power delivery could see some major restructuring. Two plenary talks (one...

    How to tame EMI noise in your power-supply design

    Let’s say you are designing a buck power supply for a combustion engine application (a lawn mower, chain saw or automobile). For this application, you know you will need to meet a Comité International Spécial des Perturbations Rad...

    Save PCB space and overcome point-of-load design complexity with PMBus modules

    Engineers face many difficult challenges when designing power supplies for industrial and communication systems. A typical system can include one or more field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), systems-on-chip (SoC), networking and communication processors, or other types of processors. Each processor...

    Rethink compute density with GaN

    According to a report published by the Lawrence Berkeley National Laboratory in 2016, data centers across the United States consumed a whopping 70 billion kWh of energy in 2014. It comes as no surprise that the industry is continuously looking for ways to increase power efficiency and density. Higher efficiency saves both electrical and major operational...
