Most of the designs that I work on require some sort of power supply design. The power supply rails are the foundation of a good design, allowing one to hit not only the desired voltage level, but also low noise, efficiency, and EMI specifications. There are many tests a power supply design goes through before it can be qualified, however there are a few that are almost always used.
I thought I’d use my Tektronix MDO3104 to show some of the tests that are always done on a switch mode power supply design. I’ve created the video below, and written an accompanying article over at Element14.
