  • Smart meters are pretty cool. You can track your usage of water, gas, or electricity by the day or even the hour. And if your water, gas, or electric service is disrupted, the smart meter is kind enough to automatically report this outage to the utility...
  • In PC and server applications, one might choose bridgeless power factor correction circuit (PFC) , such as the one shown in Figure 1, to meet the 80 Plus Platinum or Titanium requirement. Figure 1. Power stages of bridgeless PFC circuit. When...
  • Have you ever come across a lack of performance in the signal chain only to realize the issue was originating in the power supply? In this blog, I will describe some of the issues encountered in the signal chain due to the power supply and how to resolve...
  • What do you like most about the smart thermostat in your home or office? Or, if you don’t have one yet, what do you dream of finding in a new thermostat? Is it the display that is big enough to read? Do you most value the ability to control it from...
  • Fly-Buck converters are a common topology of choice for generating low power isolated outputs, bipolar (+/-) outputs and multi-output rails. Fly-Buck topology use is common in telecom, PoE, custom PoE, industrial and automotive applications. The most...
  • While the primary goal of IEEE standards is to provide interoperability between devices that are compliant to the standards, creating standards that allow for backwards compatibility is a close second. I even wrote my first ever blog post about backwards...
  • After reading my last blog you may have considered placing the LLC series resonant converter (LLC-SRC) into your next power supply. LLC-SRCs are usually hiding behind another well regulated power stage, such as the example in Figure1. This isn’t...
  • Designing a power supply can be termed more of an art than a science. The transients and real-world interactions are simply too ornate to capture with any single model of a power supply system. Generally, these models construct some sort of transfer function...
  • There are many things that can go wrong when designing with a hot swap controller. For example, the hot swap can trip at an unexpected current value or a current monitor may report inaccurate measurements. As a result, the integrity of a system which...
  • In this day and age low power consumption is something every system is moving towards, making it a key challenge for engineers to minimize power for their application. Low power consumption is something we can all agree on especially when it results in...
