Power House

  • Last week in "Driving MSP430 low-power even lower," we discussed a particularly interesting property of MSP430: although the supply voltage range of MSP430 is fairly wide (1.8 to 3.6V), power consumption can vary depending on the specific voltage...
  • Most conducted EMI problems are due to common mode noise. Furthermore, most common-mode noise issues are caused by parasitic capacitances in the power supply. For Part I of this discussion, let’s focus on what happens when the parasitic capacitance...
  • It’s no mistake that when you think of MSP430, Texas Instrument's flagship microcontroller, low power is one of the first things that comes to mind. After all, this is why MSP430 is such a popular choice for battery-powered applications. By...
  • Note - Originally posted by Jacob Ontiveros on Analog Wire here .. 1080p video screen resolution is in almost every home, and like technology does these days, it’s quickly evolving to the next step: 4k video. This presents many challenges for...
  • Synchronous buck converters have gained acceptance as isolated bias supplies in communications and industrial markets. Isolated buck converters, or Fly-Buck™ converters as they are commonly called, have a coupled inductor in place of the buck converter...
  • For the past few years as a design and field applications engineer at Wurth Electronics Midcom, I have been working with engineers to develop custom transformers. In the world of custom magnetics, it is sometimes nick-named ‘black magic’,...
  • When I was in high school, I worked at a local fast food restaurant. Rather than save the money I earned for college, or something else more practical, I invested in something else - car audio. I had a Toyota Corolla with a hatchback. It was a junker...
  • The IEEE802 March 2014 Plenary Session was held last week in Beijing, China. For me, it was my first time in Beijing and my first real chance to do any sort of sightseeing in China. I was able to squeeze in visits to both the Great Wall and the Forbidden...
  • This blog originally appeared on Planet Analog . On Wednesday, APEC held their annual social event, this year at the home of the Dallas Cowboys, the Fort Worth AT&T stadium. The playing field was definitely big enough to accommodate all of us....
  • If you happened to be at APEC this week, I hope that you had a chance to stop by the TI booth and check out the demos of our integrated 700V switchers. It has been a fun and exciting way for us to showcase our entrance into the high voltage integrated...
