Ringing is a common term that refers to the undesired oscillation which happens when a power semiconductor switch turns on or off in the presence of parassitic inductance and capacitance. In this podcast, learn how ferrite beads placed in series with the bootstrap pin of buck regulators can make excellent ringing control components, and when applied properly they can be used to treat the source of the high frequency noise without taking up too much PCB area.
