Abstract
The present document relates to power converters with multiple feedback loops. The present document relates to a power converter with at least two feedback loops. The power converter may comprise a first error amplifier and a first capacitive element. The power converter may comprise a second error amplifier and a second capacitive element, wherein the second error amplifier is configured to generate, based on a second reference value and a second feedback signal, a second error current for charging the second capacitive element. The power converter may comprise a selector circuit configured to generate a selection signal by comparing a first voltage of the first capacitive element and a second voltage of the second capacitive element. The power converter may comprise a first track amplifier circuit configured to establish an additional current path from a supply rail to the first capacitive element for accelerated charging of said first capacitive element.
