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.

Claim (Index 1):
A circuit comprising:\n a current sensor to sense a switching current at an input side of a switching DC-DC converter; an output capacitor to filter an output voltage at an output side of the switching DC-DC converter; a feed-forward circuit that passes a portion of the sensed switching current to a feedback path on the output side of the switching DC-DC converter, the feed-forward circuit changes a frequency response of a control transfer function affected by the effective series resistance (ESR) of the output capacitor to stabilize the DC-DC converter; a current mirror to scale the sensed switching current at a ratio of M:1, wherein M represents a smaller amount of sensed output current than scaled by a scaling transistor; and a transistor pair that is driven by the current mirror, the transistor pair coupled via a low pass filter at their respective gate nodes, the transistor pair and low pass filter together to divert high pass ripple currents from the current mirror to the feedback path.
