It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response—no good reference exists that defines this in simple terms. It seems ...

Multiphase buck topology is preferred for processors that are drawing increasing amounts of current at lower voltage. Common design practices limit the open-loop bandwidth of the control system to 10% ...

Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

All power supplies require some type of feedback loop to regulate the output voltage. A simplified diagram of a buck controller is shown in Figure 1 with a pulse ...
