A load line regulated switched-mode power converter supplies an output voltage and an output current to a load. The power converter includes an inductor, a switch coupled to the inductor, a first impedance, a second impedance, and a power converter controller. The power converter controller includes a first sense circuit to obtain momentary information on a first current which flows through the first impedance, and which is related to the output current. A difference between a zero load voltage and the output voltage is determined to obtain a difference level. A second sense circuit supplies further information on a second current which flows through the second impedance, and which is related to the first current. An integrator integrates a difference between the further information and the difference level to obtain a correction signal. A switch controller receives the difference level, the momentary information and the correction signal to control the switch to obtain a substantially zero correction signal in a steady state.
