ABSTRACT:
An actuation circuit is provided for a switch controlling the power consumption in a switch-mode converter which has input terminals for applying an input voltage and output terminals for providing an output voltage. The actuation circuit comprises a first input for supplying a voltage measurement signal which is dependent on the output voltage, an error signal generation circuit which generates an error signal by comparing the voltage measurement signal with a reference signal, a filter arrangement which is supplied with the error signal and which generates a first control signal, and an actuation signal generation circuit which is supplied with the first control signal and which provides an actuation signal for the switch on the basis of the first control signal. The filter arrangement comprises a first filter with an integrating response which generates a first filter signal on the basis of the error signal, a second filter which generates a second filter signal from the error signal in accordance with a hysteresis characteristic, and a combinational logic circuit which generates the first control signal from the first and second filter signals.
