Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: quoted-printable Hi Istvan; Is this behavior common to all types of DC-DC converters (i.e. Buck, Bo= ost, etc) Topology? Is there any reference that I can find to discuss these situations?

It can affect any signal, not only reset. You need to select your converters carefully so that they do not produce too much noise an= d make sure there is no sensitive signal running too close to the converter. There are no specifications or generic rules that would wor= k for many situations; you need to look at this on a case-by-case basis.
