by Pradeep Shenoy, Texas Instruments EDN There are standard techniques to generate negative output voltages, and there are well-known approaches to dynamically adjust an output voltage. The missing link that I hope to address in this article ...

As a cautious analog-centric engineer, I have always liked traditional thermal-based fuses and been somewhat skeptical of electronic fuses (also written as e-fuses or eFuses) due to their active components. After all, when it comes to reliability, ...

Syntiant, an Irvine, California-based startup with big name backers like Intel and Microsoft, said its custom chips could be used to push Amazon's Alexa into smaller, battery-powered devices like wirebles and wireless headphones that wake ...

Nadia Krieger engineering.com Semiconductor supplier Atmosic Technologies has a three-step plan for achieving a “Forever Battery.” The company is now putting it out there in the form of two newly launched Bluetooth 5 low-power chip ...

Sam Davis Power Electronics This high-efficiency IC with charge pumps and associated circuits reduces input voltage up to one-eighth while providing a 15-W drive for external point-of-load regulators. Helix Semiconductors’ HS200 DC/DC ...

David Zhang LEDs Magazine In many solid-state lighting (SSL) applications, such as architectural, area, and downlighting, color accuracy is very important. Moreover, an increasing number of products support dynamic color tuning to set the white ...

Question: Where do I connect the grounds of switching regulators? Answer: How should you proceed with a switching regulator with an analog ground (AGND) and a power ground (PGND)? This is a question asked by many developers designing a switching ...

Bob Zollo Power Electronics You may want to double-check the dimensions of the 18650 you’re targeting for a design a built-in protection circuit could extend it past the standard size Since the late 1990s, the 18650 lithium-ion rechargeable ...

Alfredo Medina Mohamed Ismail EDN Power accumulators enable a variety of applications that require average power measurement. One example is real-time measurement of switching converter efficiency, which permits converter efficiency evaluation over ...

Alfredo Medina Mohamed Ismail EDN Part 1 PMIC Power Consumption To prolong battery life, it becomes crucial to monitor PMIC voltage rails and determine system performance based on power consumption. Power accumulation diagnostics can be used to ...
