Abstract
A buck converter has an output node and a ground node, wherein a load is connected between the output node and the ground node and is arranged to drive an output current I_out through the output node, generating an output voltage V_out. A current control unit arranged to control the output current I_out in dependence on a control voltage V_ctl provided at a control node; and a voltage control unit arranged to provide the control voltage V_ctl. The voltage control unit comprises: an integrator unit arranged to control the control voltage V_ctl in dependence on a time integral of a difference between the output voltage and the reference voltage; at least one of an overshoot detector arranged to detect an overshoot of the output voltage V_out, and an undershoot detector arranged to detect an undershoot of the output voltage V_out.
