I'm frequently asked why I refer to the effective inductance of a voltage reference, voltage regulator, or op-amp in my articles. Others question “Is there really an inductor in there?”, “Where does ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

For the PDF version of this feature, click here. Hysteretic control, also known as bang-bang control or ripple regulator control, maintains the converter output voltage within the hysteresis band ...
