Abstract
A power stage of a multi-phase power converter includes: a first switch device configured to connect an output node of the power stage to a supply voltage in a first switching state of the power stage; a second switch device configured to connect the output node to ground in a second switching state of the power stage; driver circuitry configured to set the power stage in either switching state or a non-switching state, a duration of each state and a timing transition between the states being indicated by a control signal; current sense circuitry configured to measure current flowing through at least one of the switch devices; and timing circuitry configured to adjust the timing transition between switching states so as to change an effective duration of the first and/or second switching state relative to a reference duration defined by the control signal, based on magnitude of the measured current.
