Patent ID: 7312597

Claim:
An actuation circuit for a switch that controls the power consumption in a switch-mode converter, the switch-mode converter having input terminals for applying an input voltage and output terminals for providing an output voltage, the actuation circuit comprising: an error signal generation circuit configured to generate an error signal based on a reference signal and a voltage measurement signal, the voltage measurement signal dependent on the output voltage, a filter arrangement including a first filter having an integrating response and configured to generate a first filter signal from the error signal and a second filter configured to generate a second filter signal from the error signal in accordance with a hysteresis characteristic, the filter arrangement configured to generate a first control signal based on the first filter signal and the second filter signal, an actuation signal generation circuit configured to generate a switch actuation signal based at least in part on the first control signal, the actuation signal generation circuit adapted to provide the switch actuation signal to the switch.
