Abstract:
A circuit includes a current sensor to sense a switching current flowing at input side of a switching DC-DC converter. An output capacitor filters an output voltage at an output side of the switching DC-DC converter. A feed-forward circuit passes a portion of the sensed switching current to a feedback path on the output side of the switching DC-DC converter simulating a changing effective series resistance (ESR) of the output capacitor to facilitate operating stability in the switching DC-DC converter.
