WebBefore designing the filter, consider what is achievable with a single stage filter RC or LC filter. Typically with a second stage filter it is reasonable to get the ripple down to a few hundred μV p-p and the switching noise down below 1 mV p-p. A buck converter can be made somewhat quieter since the power inductor provides significant filtering. WebProgrammable devices are also available to help design buck converters fine-tuned for specific EMI, EMC, efficiency and power density targets and use cases. We have also …
