Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

This file type includes high resolution graphics and schematics when applicable. Switching power supplies are inevitable in today’s designs. They’re power-efficient and thermal-efficient, with various ...

An effective and long-lasting power supply is the backbone of any IoT device. Switch-mode power supplies (SMPSs) are undoubtedly good for powering IoT devices, but most of them are bulky and expensive ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Editor’s note: I hope to see many of my EDN and Planet Analog audience at APEC in Tampa, FL this year. Texas Instruments will have Bob Mammano at their booth at APEC where you can meet him and enter ...

The common type of power supply used with computers and other electronic equipment. The "switching" comes from switching a transistor on and off to create square waves for input to a transformer. For ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

[Hesam Moshiri] has built a variable switch-mode power supply over on hackaday.io. When prototyping a new circuit, often the goal is to get a proof-of-concept working as soon as possible to iron out ...

The power supply unit inside of an ASUS computer is responsible for providing power to all of the components inside of the PC. Some of these components are integrated into the motherboard – including ...

Every single desktop PC, console, or laptop has one of these. It won't boost your frame rate, nor does it have billions of transistors, and it's not manufactured using the latest chip process nodes.
