High efficiency and, hence, low loss is a usual design goal for a PWM circuit. Figure shows one of several channels of low-loss PWM control for hydraulic valves used in heavy industrial machinery...

For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as LM317, offer ease of use, low cost, and full on-chip overload protection...

You can use monolithic linear regulators at currents lower than 5 A for most applications. Most manufacturers of these devices integrate current-limiting and thermal shutdown to prevent damage during fault conditions...

Arduino’s smallest board to date is ready to sense and make sense of the world: state-of-the-art technology meets easy-to-use versatility, in the first product launch within the new Nicla family...

I recently got an assignment to design a battery charger. I decided to use the BQ2000TSN from Texas Instruments because of its versatility in battery chemistry. In my case the battery charger is used to charge a Lithium-ion battery pack...

The circuit shows a familiar technique for converting a low-level analog signal to digital form. Resistors R1 and R2 set the quiescent dc level at the Schmitt inverter's input to a value roughly equal to the midpoint of the hysteresis band...

Cities and towns worldwide are considering and installing LED streetlights to help save electric energy, reduce costs, protect the environment, and improve lighting for their citizens. Despite this trend, the lamps’ turn-on/ turn-off time control is receiving little attention...

The new MAX77659 single-inductor multiple output power management IC with integrated switch-mode buck-boost charger from Analog Devices charges wearables, hearables and Internet of Things devices faster and in less space than any other PMIC available today...

Problems with solid-state switches are leading some electrical engineers to consider mechanical ones for digital chips. A team of engineers in Carnegie Mellon University’s College of Engineering are investigating how to develop reliable, nanoscale mechanical switches...

For a variety of reasons, designers often discover that their creations need yet more power-supply voltages. For example, a system powered by ±2.5 V power supplies suddenly needs a precision –1.4 V reference for a signal-level-shifting circuit and needs a 2.1 V reference to drive an ADC...
