Abstract
A timing generator for a power converter is provided. The timing generator includes a threshold voltage generation circuit and a timing generation unit. The threshold voltage generation circuit receives an error signal related to an output voltage of the power converter. The threshold voltage generation circuit generates a threshold voltage according to the error signal. The timing generation unit generates a timing signal according to the error signal, the threshold voltage and a control signal. The timing generation unit provides a tracking signal. A width of the timing signal depends on a time when tracking signal departed from a level of the error signal to a level of the threshold voltage. The present invention also provides a timing signal generation method for the power converter.
