A DC to DC conversion circuit comprising: - a DC to DC converter comprising an inductor; and - a regulation circuit (308, 310) comprising: a comparator configured to detect, during a discharge phase (φ_DISCHARGE) of the DC to DC converter, an overshoot period during which an output voltage (VOUT) of the DC to DC converter exceeds a target voltage (TARGET), wherein during the discharge phase (φ_DISCHARGE) of the DC to DC converter, an inductor current (I_COIL) is supplied by the inductor to an output of the DC to DC converter; a timer configured to measure a duration (t_OS) of the overshoot period; a first further comparator configured to detect a rising voltage state (METRIC RISING) when the duration (t_OS) of the overshoot period exceeds a threshold level (THRD); a second further comparator configured to detect a falling voltage state (METRIC FALLING) when the duration (t_OS) of the overshoot period is lower than the threshold level (THRD); and a low pass filter configured to generate the threshold level (THRD) based on a plurality of previous values of the measured duration of the overshoot period; and a controller configured to adjust the duration of the inductor charge phase and/or inductor discharge phase of the DC to DC converter in response to the detection of the rising voltage state and of the falling voltage state, so as to stabilise the overshoot duration. - a DC to DC converter comprising an inductor; and - a regulation circuit (308, 310) comprising: a comparator configured to detect, during a discharge phase (φ_DISCHARGE) of the DC to DC converter, an overshoot period during which an output voltage (VOUT) of the DC to DC converter exceeds a target voltage (TARGET), wherein during the discharge phase (φ_DISCHARGE) of the DC to DC converter, an inductor current (I_COIL) is supplied by the inductor to an output of the DC to DC converter; a timer configured to measure a duration (t_OS) of the overshoot period; a first further comparator configured to detect a rising voltage state (METRIC RISING) when the duration (t_OS) of the overshoot period exceeds a threshold level (THRD); a second further comparator configured to detect a falling voltage state (METRIC FALLING) when the duration (t_OS) of the overshoot period is lower than the threshold level (THRD); and a low pass filter configured to generate the threshold level (THRD) based on a plurality of previous values of the measured duration of the overshoot period; and a controller configured to adjust the duration of the inductor charge phase and/or inductor discharge phase of the DC to DC converter in response to the detection of the rising voltage state and of the falling voltage state, so as to stabilise the overshoot duration. a comparator configured to detect, during a discharge phase (φ_DISCHARGE) of the DC to DC converter, an overshoot period during which an output voltage (VOUT) of the DC to DC converter exceeds a target voltage (TARGET), wherein during the discharge phase (φ_DISCHARGE) of the DC to DC converter, an inductor current (I_COIL) is supplied by the inductor to an output of the DC to DC converter; a timer configured to measure a duration (t_OS) of the overshoot period; a first further comparator configured to detect a rising voltage state (METRIC RISING) when the duration (t_OS) of the overshoot period exceeds a threshold level (THRD); a second further comparator configured to detect a falling voltage state (METRIC FALLING) when the duration (t_OS) of the overshoot period is lower than the threshold level (THRD); and a low pass filter configured to generate the threshold level (THRD) based on a plurality of previous values of the measured duration of the overshoot period; and a controller configured to adjust the duration of the inductor charge phase and/or inductor discharge phase of the DC to DC converter in response to the detection of the rising voltage state and of the falling voltage state, so as to stabilise the overshoot duration. a second further comparator configured to detect a falling voltage state (METRIC FALLING) when the duration (t_OS) of the overshoot period is lower than the threshold level (THRD); and a low pass filter configured to generate the threshold level (THRD) based on a plurality of previous values of the measured duration of the overshoot period; and a controller configured to adjust the duration of the inductor charge phase and/or inductor discharge phase of the DC to DC converter in response to the detection of the rising voltage state and of the falling voltage state, so as to stabilise the overshoot duration.
