WebThe most commonly used switching converter is the Buck, which is used to down-convert a DC voltage to a lower DC voltage of the same polarity. This is essential in systems that use distributed power rails (like 24 V to 48 V), which must be locally converted to 15 V, 12 V or 5 V with very little power loss. WebJun 13, 2024 · The basic idea here is that your switcher is going to generate noise at the switching frequency and at harmonics of the switching frequency. This plot is used courtesy of Analog Devices, taken from an article on switching-regulator output artifacts. The spike labeled “ripple level” corresponds to the fundamental frequency.
