Abstract
The present document relates to power converters. In particular, the present document relates to a scheme for operating a low side switch of a power converter in the safe operation area. A power converter converting an input voltage to an output voltage is described. The power converter comprises a low side switch configured to couple an inductor to ground during an on-state of the low side switch; wherein the inductor is configured to store energy to be provided to a load at the output of the power converter; and a protection switch in parallel to the low side switch, configured to reduce a voltage drop across the low side switch during at least part of a switch off time of the low side switch.
