Abstract
The present disclosure provides a droop voltage generation circuit, a switching power supply and a droop voltage generation method. The circuit includes a reference current generation unit, a first regulation unit and a second regulation unit. The reference current generation unit is configured to generate a plurality of reference currents according to the output current of the switching power supply. The first regulation unit is configured to generate a regulation current according to a first regulation code and the plurality of reference currents. The second regulation unit is configured to generate the droop voltage according to a second regulation code and the regulation current, wherein the first regulation code and the second regulation code can be configured at least according to a target value of load line resistance. The present disclosure achieves higher accuracy and wider range of regulation of load line resistance with adjustable gain.
