<p>It is presented a switched-mode power converter comprising: a first switch configured to be used for effecting a desired output voltage or a desired output current on an output of the switched-mode power converter; and an over-voltage controller configured to detect an input voltage and to control the first switch. The over-voltage controller is configured to, as a result of detecting an over-voltage of the input voltage, decrease a resistance of the first switch such that any over-voltage on the output is attenuated. A corresponding method is also presented, as well as the switched mode power converter comprised in a mobile communication terminal and a charger for electronic apparatuses.</p> |
