  • Duty cycle dependent non-linear slope compensation for improved dynamic response
    Patent number: 8004253
    Abstract: A two-stage converter including a buck converter and a DC-DC converter that receives power from the buck converter. The DC-DC converter generates an output voltage of the two-stage converter. A buck control circuit generates a drive signal for the buck converter. The drive signal is based on a first signal representing the output voltage, a second signal representing load applied to the buck converter, and a compensation signal. A characteristic of the compensation signal varies based on the drive signal.
    Type: Grant
