Gallium-nitride (GaN) FETs are increasingly finding use as high power devices for power electronics systems. They can realize ultra-high power-density operation with low power loss due to high carrier mobility in the two dimensional electron gas (2DEG) channel. GaN FETs are a majority carrier device, therefore, the absence of reverse recovery charge creates a good match for high-voltage operation.   To learn more about how a GaN FET power stage can outperform Silicon MOSFETs, read the att ...
This is my fourth post on the TI FR2xx microcontrollers that feature FRAM memory.  The links to the previous posts are at the bottom of this post.   Introduction   I saw today where the MSP-EXP430FR2433 LaunchPad has been added to Energia, a modified version of the Wiring/Arduino IDE for select Texas Instruments microcontrollers and LaunchPads.   Energia   I have used Energia quite a bit in the past and most Arduino code and libraries will run on it, or at least port ...
Back in October, we launched a giveaway contest for the "new" Texas Instruments' Fundamentals of Power Supply Design Book. To compete in the contest, all you had to do was write a blog on the topic of TI power supply design and post it in the Texas Instruments Group.   About the Fundamentals of Power Supply Design Book This well-written, superbly illustrated, and easy-to-read reference book was written by Bob Mammano, a power supply industry expert, who is considered the father of the Pu ...
This is my third post on the TI FR2xx microcontrollers that feature FRAM memory.  The links to the previous posts are at the bottom of this post.   Introduction   The small breadboard breakout I designed for the FR2000 and FR2011 arrived in the mail today.  I was lucky and OshPark put my PCB alongside a rush order and I received it one week from submission - great!  I soldered it up and got it to blink without a problem - again, great!  In this post I will describ ...
Introduction I previously made a post on the MSP430FR2000 but decided to expand it into a more general series on the MSP430FR2xx family of microcontrollers.  I will aim this at people with microcontroller experience who may not be familiar with the MSP430 microcontrollers and FRAM (Ferromagnetic RAM).  In this post I will show how FRAM can retain the contents of a variable in memory for future use, even if power is lost.   The FR2xx series is a relatively low cost line with memo ...
Introduction This is my first look at the Texas Instruments MSP430FR2000 microcontroller.  It got my attention because of this recent post at Texas Instruments:  http:/
ewscenter.ti.com/2017-11-08-Texas-Instruments-offers-25-functions-for-25-cents-with-new-MSP430-TM-microcontrollers Twenty five functions for 25 cents sounds pretty good but be aware that if you are a hobbyist buying in small quantities you won’t be able to get these MCUs for anywhere near 25 cents.  However, ...
I have already a book of Mike Engelhardt: The LTSpice IV Simulator: Manual, Methods and Applications and I have read it from power applications perspective. But it was Linear chips approach and their chips. So now I would like to take another point of view-TI's. And i would like to simulate all the examples from the book in a free open source Falstad interactive circuit simulator and maybe even send some patches to it. Of course I would share the circuit files here on the element14. ...
Every electronics hobbyist is using a power supply of some kind. You might start with a simple battery, but sooner or later you get yourself a 'real' power supply. Probably (right behind after blinking an LED) it the most frequent DIY-project. I'm no exception for that - actually I did three of them. But they are all based on the venerable LM317, since its so easy to use. The other part one comes into contact with all the power supply issues is when you need to power your project. One might get ...
Nowadays there is a big hype about IoT devices and it’s not surprising. Many creative project and business idea is based on this new technology, the opportunity is limitless. I also had a good project idea – to design a battery operated motion sensor device. First I started to think on system level, and later on I have realized that as always, the power supply circuit is one of the most critical part of the design. A battery operated IoT device has to have low power consumption and ...
Before I write how and why I started using TI ICs for designing power supplies let's take a look at my past projects. I often design analog circuits and microcontroller based projects. Since, I need portability in most of my projects I used to use the cheap 9V batteries. Initially, they worked good in the testing phase and I didn't have any knowledge about capacity of the battery or I didn't care about the capacity. But until one day when I designed an analog line following robot with LM358 D ...
I would like to be considered for a copy of Bob Mammano's Power Supply Design book for the following reasons...   First of all; it looks like the ideal companion book to sit beside my "Art of Electronics".   Also, for many years now when I have needed a power supply I have been rather lazy; opting for a simple linear regulator and wasting power as heat or buying the cheapest board available off the internet. However there is an increasing number of times I'd like to find a better sol ...
Introduction The Texas Instruments product range has thousands of interesting power supply and related integrated circuits. I thought it could be interesting to review a few designs I’ve experimented with, and discuss what particular devices were used.   Powering an iPod/iPhone for Automotive Use This is a snippet of a schematic from an in-car project – this is the iPod/iPhone charger portion of the circuit using the TPS40200 as a step-down controller. I’ve used it for man ...
TI not only makes a lot of great hardware for designers, but also has a lot of great software tools. One tool that I have used for many years is a power supply design program called Switcher Pro. It makes power supply design as easy as inputting a few parameters and picking one of TI's many power devices. Updates for Switcher pro ended in 2011, and its features were integrated into TI's new online application, WebBench Power Designer.   WebBench has all the power tools of Switcher Pro ...
I have been building power supplies since I was 11 year old.  The first was when my father's friend gave me a few boxes of ham radio parts he didn't want when he moved to Florida. I had dozens of vacuum tubes, and no way to light them up.  A trip to Radio Shack, and a few days reading up at the library later, I had a transformer plugged into the wall, and a bright tube filament at the other end. I remember blowing up many LEDs with a 9V battery before learning about current limiting ...
Texas Instruments recently released a book on the Fundamentals of Power Supply Design. It 's written by Bob Mammano, a power supply industry expert who is considered the father of the Pulse Width Modulation (PWM) Controller. It's a interesting mix of power supply fundamentals along with a history of the power supply industry of which Texas Instruments has played an important part in developing.   It's written for the beginner as well as the expert, covering power supply basics such as volt ...
