A four-quadrant dc-dc converter offers an elegant way to control currents and voltages, and is able to set current to any level. While simple voltage converters can generate a fixed output voltage from an input voltage, this behavior isn’t ...
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 ...
