Abstract:
The invention relates to an electronic device and a method for DC-DC conversion using a comparator for generating an output signal for driving a power switch of a switch mode DC-DC converter. The electronic device is configured to reduce a bias current of the comparator with a first slope in response to a decreasing load and to increase the bias current of the comparator with a second slope in response to an increasing load, wherein the second slope is steeper than the first slope.
