Abstract

Embodiments of current feedback circuits for Direct Current (DC)-DC converters and methods for operating current feedback circuits for DC-DC converters are described. In one embodiment, a current feedback circuit for a DC-DC converter includes a current replication circuit configured to provide current feedback to the DC-DC converter based on an on-time of the DC-DC converter and an alternating current (AC)-coupling circuit configured to add the current feedback to a regulation circuit of the current feedback circuit and to remove a DC voltage from the current replication circuit. The regulation circuit includes a filter circuit configured to compensate for an offset of an output voltage of the DC-DC converter caused by the current feedback. Other embodiments are also described.
