Abstract
A transient response enhancement circuit for buck-type voltage converters, wherein, the transient load changing detecting module detects the output voltage of the buck-type voltage converter. The first control signal is generated when the increase of the output voltage is detected, and the second control signal is generated when the decrease of the output voltage is detected, thereby self-adaptively detecting the time of the buck-type voltage converter in response to the load changing. The compensation voltage predicting operation module predicts and adjusts the compensation voltage and the adjusted compensation voltage is superimposed on the buck-type voltage converter through the internal active compensation module to adjust the duty ratio of the buck-type voltage converter. The drive controlling insertion logic module can further improve the response speed.
