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 ...

The best news when you power up a prototype supply board for the very first time is when it not only works, but also runs quiet and cool. Unfortunately, this does not always happen. A common problem ...

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 ...

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 ...

The two major classes of EMI noise are conducted and radiated. Understanding the sources of noise and the correct solutions will help designers minimize their effects in switching power supplies and ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

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 ...
