Abstract
A voltage converter comprises an input, an output and a current control arrangement for controlling the output current of the voltage converter circuit. The current control arrangement comprises a first mode, when the voltage output by the converter circuit is above a threshold voltage, and a second mode in which the voltage output by the circuit is below the threshold voltage. The first and second modes are controlled by the same current control arrangement. The current control arrangement comprises comparing means arranged to receive a reference voltage wherein the reference voltage is a voltage offset associated with at least one of the inputs of the comparing means.
