  • When I started working in the IC industry many years back, I imagined a trend of higher integration with everything but the kitchen sink in one IC. That’s why I chose to work for a semiconductor company. I expected all electronics products would...
  • The Fly-Buck ™ converter topology is recognized as a versatile isolated bias power supply and is gaining more and more traction in various types of applications. A synchronous buck converter can be configured as a Fly-Buck, but not all control methods...
  • While it may seem like a long time, the recently adopted and unveiled first official timeline to publication of the new 4-Pair PoE standard targets early 2017. Still, there is plenty of work left to be done. As the PoDL task force is still in the...
  • Or, when is a Fly-Buck better? Figure 1. Isolated Converters (Topology vs. Power) There are a wide variety of applications that require bias rails, which must be isolated from the main power source. Traditionally, engineers have...
  • by Vijay Choudhary and Sourav Sen, Texas Instruments In part one of this blog series on Fly-Buck ™ topology, we introduced the reason and the idea for a secondary compensation loop for the isolated side. In this entry, we will review the compensation...
  • Efficiency versus load current with Vout = -5V In many applications, such as temperature sensing , two supply voltages are needed to power an op amp in the system—one positive and one negative. This dual supply is needed by the amplifier in order...
  • by Vijay Choudhary and Sourav Sen, Texas Instruments Over the last few years, Fly-Buck™ topology has received quite a bit of interest from designers of various industrial applications. The Fly-Buck isolated topology provides a cheaper alternative...
  • Daniel Fernsebner is a guest blogger and director of global services and developer network at Altium. For many years, Texas Instruments and Altium, the provider of Altium Designer 3D PCB design software, have worked independently to bring you tools...
  • PFC-SEPIC LED Drivers - wow, that’s a lot of acronyms! PFC stands for “power factor correction” SEPIC stands for “single-ended primary inductor converter;” And, of course, the LED stands for “light-emitting...
  • The next IEEE 802.3 Plenary Session, to be held in San Diego, California, is only a few weeks away. During the meeting, I will be presenting on an important topic that has yet to be investigated thoroughly: Can you safely apply power to equipment connected...
