Abstract
A circuit configuration for driving a pulse width modulator in a switched mode power supply includes a difference formation stage having a first input terminal for receiving a control signal, a second input terminal for receiving a reference signal, and an output terminal for providing a drive signal. The difference formation stage forms a difference signal from the control signal and the reference signal, and amplifies the difference signal by a gain factor dependent on the drive signal and/or control signal. The difference formation stage includes a multiplier and a feedback path. The multiplier includes a multiplier output connected to the output terminal, a first multiplier input terminal for receiving the amplified difference signal, and a second multiplier input terminal. The feedback path has an output connected to the second multiplier input terminal and includes an amplifier having a gain range extending between a top limit and at a bottom limit. The amplifier produces, based on the drive signal, a first constant output signal if the drive signal has a value below a first limit value, and a second constant output signal if the drive signal has a value above a second limit value.
