A good switching power supply requires a good printed circuit board. In order to make an efficient one, the PCB designer should understand the phenomenon behind the operation of the typical switching ...

We’ve often heard you should do everything twice. The first time is to learn what you need to do, and the second time is to do it right. We bet [Ian Carey] would agree after taking his old linear ...

A significant challenge in power supply design is creation of the PCB layout. Until today, design engineers relied on application notes, manual copying of reference layouts and their own judgment to ...

Some handy methods to reduce EMI levels in power supplies. EMI sources in a switch-mode power supply. The importance of PCB layout in diminishing EMI. Modern electronic systems are becoming ...

Texas Instruments (TI) unveiled WEBENCH® PCB Export, a new feature in TI's online WEBENCH Power Designer tool that engineers can use to quickly create a power supply printed circuit board (PCB) layout ...

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

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 ...

Decreased system reliability due to overloaded power supplies is a common engineering challenge. In this Q&A-style article submitted by Allied Electronic & Automation, David Norton, technical ...
