Abstract
A method for regulating a clocked buck/boost converter, wherein a buck converter switching element is driven at a common clock frequency with a first pulse-width-modulated switching signal and a boost converter switching element is driven with a second pulse-width-modulated switching signal to convert an input voltage into a regulated output voltage, and a regulator signal from an output voltage regulator is used to generate the first and second pulse width modulated switching signals such that the buck converter is operated in a discontinuous mode with quasi-resonant switching, where the inductor current or the current through the buck converter switching element is detected and compared with a reference current, where the regulator signal is amplified to the extent that the reference current is reached, in terms of time, before a turn-off pulse of the first pulse-width-modulated switching signal, and where the second pulse-width-modulated switching signal is generated using the amplified regulator signal.
