Abstract: An apparatus includes a boost converter. The boost converter includes a switch and a boost loop filter coupled to the switch. The boost converter also includes a peak current adjustment circuit coupled to the boost loop filter, wherein the peak current adjustment circuit comprises a comparator and a gain control circuit coupled to differential inputs of the comparator. The boost loop filter is configured to provide a control signal to the switch based on an output voltage of the boost converter and a peak current adjustment provided by the peak current adjustment circuit.
