RIPPLE SUPPRESSION IN MULTI-PHASE BUCK CONVERTERS

Abstract:

Methods and systems for ripple suppression in multi-phase buck converters may comprise a buck converter for providing an output voltage with controlled ripple current. The buck converter may include one or more main buck converter stages and one or more suppression buck converter stages coupled with the one or more main buck converter stages. The one or more suppression buck converter stages may provide suppression currents to reduce ripple currents generated in the one or main buck converter stages.
