Abstract
A step-up converter includes input and output terminals, step-up conversion circuitry, a first feedback path and a drive circuit. The input terminals are configured to receive an input DC voltage and the output terminals configured to provide an output DC voltage. The step-up conversion circuitry is coupled between the input terminals and the output terminals and includes a switching element. The first feedback path has a regulator arrangement configured to provide a regulating signal which is dependent on the output voltage. The drive circuit is configured to provide a pulse-width-modulated drive signal for the switching element and is supplied with the regulating signal, wherein the drive circuit is configured to generate the drive signal in a manner that corresponds to the input voltage.
