Low Noise Power Supplies Come in Many Flavors: Part 3 - Buck Converters

Kevin B. Scott - Senior Strategic Marketing Engineer
Tim Sourdif - Senior Design Engineer
Mar 23rd 2017
In Part 1 of the series, we looked at linear regulators for lowest output noise performance. In Part 2, charge pump solutions with integrated post linear regulators we highlighted. In these previous examples, circuit efficiency was a lower priority. But what if low output voltage noise and high efficiency are both desired? ...
