What is PCB Data Management
Managing your PCB design data is the key to a trouble-free design process. In this article, expert Mark Harris will discuss PCB design data verification, management, maintenance and security.
Common Mode Choke Selection
Noise on power supply lines can be a major headache, causing reliability issues and leading to unexpected system behavior. Let’s discover how selecting the right choke could prevent this.
Ferrite Core Selection and Design Decisions
When designing a transformer or inductor, you must use the correct design process, and there is no substitution for real-world final testing. Let’s look at the process.
Controlled ESR Capacitors: Should You Use Them for Power Integrity?
I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of
Voltage Derating for Ceramic Capacitors
Operating just about any type of capacitor below its maximum rated voltage ensures a longer operating life. Such components’ performance will degrade in response to the application of voltages approaching their rated limit and exposure to high temperatures. By choosing to limit the applied voltage, such effects can be reduced. Ceramic capacitors are one of the most common types of capacitors that are in use today thanks to their compact packaging
Resistor Derating to Improve Mean Time Between Failure
All resistors have a specified power rating that determines the maximum energy they can convert without its performance degrading or the component failing. Read now to learn more.
Methods to Protect your Circuit
Overvoltage, overcurrent, and heat are the three most likely events that can destroy our expensive silicon-based components or reduce our product’s life expectancy. The effects are often quite instant, but our product might survive several months of chronic overstress before giving up the ghost in some cases. Without adequate protection, our circuit can be vulnerable to damage, so what should we do? Or do we need to do anything? For instance, if
Power supplies - Buy, Outsource, or Design
There is more stress on a power supply compared to most of the other parts of our design. Mark Harris addresses the most pertinent issues to consider and, in several places, adopt a checklist format for you to use. Read now.
Testing the Limits of Your LDO's Efficiency
The efficiency of your LDO isn’t a fixed value, but neither is your maximum current output. Read about your LDO efficiency curve to better see why LDOs have narrow operating ranges.
Should You Route Signals in Your PCB Power Plane?
Before you cut up your PCB power plane with signals, pay attention to things like impedance control power plane current capacity to ensure reliability.
How Total Harmonic Distortion Affects Your Power System
