    Abstract: A boost converter for converting between an input voltage and an output voltage is disclosed. The boost converter includes an inductor connected to the input voltage a switching arrangement for controlling the switching of the inductor current to an output load at the output voltage and a controller for controlling the switching arrangement to provide duty cycle control. The duty cycle control switching takes place when the inductor current reaches a peak current level which varies over time with a peak current level function. The peak current level function includes the combination of a target peak value derived from a target average inductor current and a slope compensation function which periodically varies with a period corresponding to the converter switching period.

    Abstract: A circuit for a switched-mode-power-supply. The switched-mode-power-supply is configured to: receive a current-control-signal; and provide an output-voltage based on the current-control-signal. The circuit comprises a controller, a current-limiter and a clamp-circuit. The controller is configured to: generate a control-voltage based on the difference between: (i) a sense-voltage, which is representative of the output-voltage of the switched-mode-power-supply; and (ii) a reference-voltage; generate a target-current-control-signal based on the control-voltage, wherein the target-current-control-signal is configured to adjust the current through the switched-mode-power-supply in order to bring the sense-voltage closer to the reference-voltage. The current-limiter is configured to provide the current-control-signal as the target-current-control-signal limited to a max-current-control-value. The clamp-circuit is configured to set the control-voltage to a clamp-voltage-value when the current-limiter provides the current-control-signal having the limited value of the max-current-control-value.
