Patent ID: 8810157

Claim:
A feedback sense circuit for a power converter, wherein the power converter transfers current from an input port to a regulated output through an inductor during an on time of a power switch, and wherein current circulates through the inductor and a freewheeling diode during an off time of power switch, and wherein switching of the power switch is controlled by a controller in response to a feedback signal received on a feedback terminal of the controller, the feedback sense circuit comprising: a sense resistor module comprising a first end and a second end, wherein the first end of the sense resistor module is coupled to a cathode of the freewheeling diode, and wherein the second end of the sense resistor module is coupled to a common coupling point of the inductor and the power switch; a first resistor comprising a first end and a second end, wherein the first end of the first resistor is coupled to the first end of the sense resistor module, and where the second end of the first resistor is coupled to the feedback terminal of the controller; and a first capacitor coupled between the feedback terminal of the controller and the common coupling point of the inductor and the power switch.
