    How to Select a MOSFET – Load Switching

    “Two roads diverged in a yellow wood, marked FemtoFET and SOT-23, So I chose the path of FemtoFET to shrink my PCB” – Robert Frost (I think) MOSFETs are being used as load switches more than they are being used in any other application, in volumes in the hundreds of millions at a time. I should probably start with exactly...

    Improving the thermal performance of a power module

    A derating curve like the one shown in Figure 1 is an essential part of making a power module easy to use. With the derating curve, you can quickly see if the power module is rated to support your particular application’s requirements. In most cases, the derating curve shows the rated output current at various ambient temperatures. Operating below...

    Powering FPGAs – Improving overshoot of voltage regulators for Intel Arria 10 and Stratix 10 FPGAs

    Previously, in my last blog “ Improving undershoot of voltage regulators for Intel Arria 10 and Stratix 10 FPGAs ” we discussed how Asynchronous Pulse Injection (API) could reduce the undershoot of a fixed frequency DC/DC converter during a...

    How to Select a MOSFET – Selection Tool

    In my last blog post , I talked about how difficult it can be to select the most appropriate field-effect transistor (FET) for switch-mode power supply (SMPS) applications. Predicting circuit performance from a data sheet specification is a tedious pr...

    Use load switches for power sequencing

    Virtually all complex processors require some kind of power sequencing at power up and/or power down. The timing requirements vary depending on processor selection and the subsystems being powered. For example, the image processor in a multifunction printer (MFP) has several rails that need to power up and power down in a specific order to properly...

    10 more reasons to start using Power Stage Designer

    Since 2011, TI’s Power Stage Designer TM has been a great design aid for many electrical engineers when calculating the currents and voltages of different power-supply topologies. It is the easiest tool to start a new power-supply design, because all calculations are executed in real time and you get a direct feedback. With the evolution from...

    Powering FPGAs – Improving undershoot of voltage regulators for Intel Arria 10 and Stratix 10 FPGAs

    An ideal power supply provides a perfect voltage and never varies. In practice, however, all power supplies have some error associated with the output voltage accuracy at steady state. Additionally, when the load current increases or decreases, the p...

    Drive LEDs in virtual reality applications

    “Virtual reality will be big.” What sounded revolutionary several years ago has become true, and the market is now maintaining strong growth. In virtual reality applications, what you might not know is that there are actually lots of light-emitting diode (LED) drivers inside. In this post, I’ll introduce the kinds of LEDs integrated...

    How to Select a MOSFET – Switch Mode Power Supply

    Perhaps the most common use for high-performance power MOSFETs in the current marketplace also presents the greatest challenge in selecting the most appropriate FET. Never are the trade-offs between performance, price and size more muddled than in th...
