Power Integrity Analysis for Your Power Delivery Network
Designing PCBs to have stable power output is as much an art as it is a science. Power integrity analysis and simulation is all about verifying a design will deliver the required power, but also that the delivered power will be stable. This idea that a power supply might not deliver stable power is not necessarily related to the power supply, it's related to the design of the PDN on the PCB. The structure of a PCB, the elements used to store and

What is SRAM? PCB Design Tips and How to Prevent Data Loss
SRAM loses its data when power is removed. One of the best inventions in editing software is the autosave feature, which prevents Murphy’s Law from striking at the worst time. Decades ago, I nearly cried when several pages of an important university assignment were literally wiped out, as the non-existence of the autosave feature was made worse by my reluctance to hit the ‘Save’ button. In electronics, you risk losing the entire data stored in a

Coupled Versus Uncoupled Inductors Procurement: Which is Right for Your Switching Power Supply?
I recently took a deep dive into the various types of topologies surrounding switching power supplies. This article examined the benefits and downfalls of some of the most common topologies and aimed to assist you in the process of choosing how to power your design. The SEPIC topology is a very common switching mode power supply that can operate as both a Buck and a Boost converter. In other words, the SEPIC can act as a step-down (Buck converter

Smart Self-Check Process to Optimize Power-Up for Embedded Systems
I’ve been obsessed with morning routines ever since I started sending my son to kindergarten in the morning. From making breakfast to ensuring that his schoolbag is properly packed, I rarely mess up, except for a rare occasion where I forgot to place his water bottle in his bag. Despite the rarity of that occurrence, my son wasn’t impressed with my forgetfulness even though I promised it wouldn’t happen again. Now, when checking through his

Managing Your Audio Power Supply Designs: Tips for Circuit Design
As I get older, I suspect I’m gradually getting deafer. My hearing was pretty sharp during my teenage years but these days, I miss out on conversations and need to frequently ask people to repeat themselves. Perhaps my hearing ability is deteriorating due to age; however, when I hear static noise creeping out of an amplifier, I know to trust my ears. In electronics, the power supply of audio circuits can mean the difference between perfect audio

DC Power Supply Protection from Unexpected Damage and Inconvenience
When it comes to parenting, I might not be the best role model. This isn’t because I don’t take good care of my only son; it’s because I’m the stereotypical overprotective dad. I fuss over tiny bruises and rush for a digital thermometer at the slightest hint of a fever. Unable to stop worrying about how my son will adapt and get along with other preschoolers, I even become an occasional nuisance at his nursery. Over time, I’m starting to realize

Power Consumption Tips: What are Ways to Reduce Power Consumption in an Embedded System?
For years, I always forgot to turn off the lights and fans at my house. Despite initially denying that constantly using these appliances significantly increased my electricity usage, I eventually broke my bad habit and began turning off every little switch. After all, being more prudent about my electricity usage reduces my monthly bills and promotes a greener earth. Unfortunately, minimizing system power consumption in an embedded system

Why Startup Transition is a Concern for Embedded Systems
Do you have a morning ritual? I can barely function without mine. My brain has a hard time operating without a big breakfast, some piping hot coffee, and five minutes browsing through my inbox even when there are zero unread emails. Having a morning ritual for your embedded system is helpful too. While you don’t need to serve any coffee to your PCB’s microcontroller, you do need to ensure that it efficiently handles the transitional state during

How an Electrolytic Capacitor PDN Issue Almost Brought Down a Building
I recently came across an interesting story that involves the tale of a boiler system that failed to start under the close supervision of a TDK-Lambda rep, only to be solved by none other than the building maintenance technician. The story starts by the shutdown of an aging boiler in the dead of winter a British winter that required replacement of the seven-year-old radiators. After the repair and replacements took place, the boiler was switched

Voltage Regulators and How to Plan Your Power Budget with PDN Analysis and Examples
With my first buck regulator design, I had been given a power budget for the circuit block and I had to take into consideration what it was supplying and what topology I’d use. I considered efficiency to remove heat from the enclosure and I wanted to avoid using a heat sink. I also wanted a robust engine, a regulator to keep on working when the CPU, memory, and other utility circuits were exercising their might. I decided on the buck regulator

High Currents and High Temperature: PCB Design Tips for Heat Management
I remember the first (and hopefully the only) time one of my circuits caught on fire. It started with the resistors and quickly spread to a nearby decoupling capacitor. Thankfully, the destruction was minor and most of the components were salvageable. Why did this happen you ask? No, this was not due to a short circuit. Very simply, I did not take into account the high current PCB layout. As electronics continue to be miniaturized, the thermal

Universal Language: PCB Design to Minimize EMI in Communications Systems
Can you imagine what a world without lines would be like? At first, it seems wonderful to not have to wait around anymore, trusting that people will figure their business out. Disneyland, happiest place on Earth, receives about 44,000 people per day. Imagine a thousand people all rushing to get on the next available log flume. No longer just a tower of terror, but a whole theme park. When designing PCBs, your traces are the lines and each has a

Be the Expert When it Comes to Designing Your Power Distribution PCB
Editorial credit: Paolo Bona / Shutterstock.com Around my house, we seem to undergo a transformation to obscure-sport experts every four years, and coincidentally it occurs at the same time that the Winter Olympics is taking place. Yes, I’m talking about the sport of curling. We have all become subject matter experts in the “button,” the “hammer,” the “house,” “sweeping,” and of course the “curl.” Rest assured, by next month we will have

For Your DC Power Application, Which Switching Power Supply Topology is Right?
We often have our old-timer pioneers to thank for laying down the groundwork for our continued success and future growth. These old-school designers had nothing more than theory and confidence to drive their designs, or more specifically, to drive their failures. But as stated by a multitude of wise individuals, each failure is nothing more than a discovery of how not to do something. However, with the discoveries of failures also come
