Increasing power conversion efficiency and power density has always been the primary goal for the power supply industry. Over the past decade, there has been phenomenal progress thanks to the development of power devices, topologies, and control ...

Voltage supervisors have provided analog voltage monitoring to digital circuits for decades. Texas Instruments released the original TL7705 in 1983; it consumed 1.8 mA, came in a plastic dual-inline package (PDIP) and you can still purchase it ...

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 ...

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 hundred millivolts ...

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 ...
