A switching regulator can be constructed either monolithically or via a controller. In a monolithic switching regulator, the respective power switches, usually MOSFETs, are integrated within a single silicon chip. With controllers, in addition to ...
Design Note 391 Introduction Handheld designers often grapple with ways to de-bounce and control the on/off pushbutton of portable devices. Traditional de-bounce designs use discrete logic, flip-flops, resistors and capacitors. Other designs ...
Electronic Design By adding a resistive divider and dc voltage to a standard dc-dc regulator, you can easily develop dc rails below 1 V, all the way down to just a few hundred millivolts. You can generate a tiny dc supply voltage of a just a few ...
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 combines both techniques with a simple ...
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 ...
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 MuxCapacitor Power IC is a new type ...
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 ...
