Abstract
A control circuit for a switching converter having a comparison circuit, a synchronization unit, an ON-time control circuit and a logic unit, the comparison circuit provides a comparison signal based on a reference signal and an output signal of the switching converter, the synchronization unit provides a first synchronization signal and a second synchronization signal based on a first clock signal, a second clock signal and the comparison signal, the first synchronizing signal is generated by synchronizing the comparison signal with the first clock signal, the second synchronizing signal is generated by synchronizing the comparison signal with the second clock signal, the ON-time control circuit provides an ON-time control signal, the logic unit provides a switching control signal to control the switching converter based on the first synchronization signal, the second synchronization signal and the ON-time control signal.
