1. A method for operating a voltage step-down switched mode power supply, the method comprising:

  • delivering an output voltage with an output stage having a power transistor that is cyclically made conducting by a first control signal; and

    when operating the switched mode power supply in a pulse width modulation (PWM) mode,generating an error voltage based on the output voltage and a reference voltage; and

    applying a first delay on the first control signal, the first delay being determined so as to reduce a difference between the error voltage and the reference voltage.
