The first thing you may want to do is check if the default control loop (i.e. the PID settings that the product is delivered with) is good enough in terms of stability and load transient performance.

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Just recently, I was eavesdropping on several engineer acquaintances of mine discussing bypass capacitors. Also known as decoupling capacitors, these capacitors are everywhere. Some products contain ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

Editor’s note: The following is Part one of a technical white paper by Ericsson with some very educational and practical design information. The paper discusses the Loop Compensator and Capacitor ...
