Abstract:
A switching converter providing an output voltage has at least one switch and a control circuit. The control circuit has a slope compensation module, an output correction module and a control module, wherein the slope compensation module provides a slope compensation signal, the output correction module provides a voltage trim signal based on the slope compensation signal, and the control module provides a control signal to control the at least one switch based on the slope compensation signal, the voltage trim signal, a reference signal, the output voltage and an error compensation signal provided based on a difference between the output voltage and a set target of the output voltage.
