Abstract
A buck switching converter is calibrated using a method which alternates between first and second calibration phases. During each first calibration phase: a time period of low-side switch on state is kept constant and, for each current pulse in an inductor, a sign of a value of the current at the end of the time period of on state of the low-side switch is determined. Modification of a time period of high-side switch on state is made based on the determined sign. During each second calibration phase: a time period of high-side switch on state is kept constant and, for each current pulse in the inductor, a value of the current at the end of the time period of on state of the high-side switch is compared with a target value. Modification of the time period of low-side switch on state is made based on the comparison.
