A switching mode power converter circuit and a method are presented. The circuit comprises a first transistor switch and a second transistor switch coupled in series between an input voltage level and ground. There is a control circuit for controlling switching operation of the first transistor switch and the second transistor switch. There is a detection circuit for sensing a voltage at an intermediate node arranged between the first transistor switch and the second transistor switch, for deriving an indication of a slope of the sensed voltage, and for generating a switching control signal for the control circuit on the basis of the derived indication of the slope of the sensed voltage. The control circuit sets a first timing for activating the first transistor switch and/or a second timing for activating the second transistor switch on the basis of the switching control signal.
