Abstract
A switching regulator configured to provide an output voltage comprises a power stage, an error correction circuit, a comparator, an ON-time generator and a logic circuit. The error correction circuit generates an error correction voltage based on a reference voltage and a feedback voltage representative of the output voltage. The comparator compares the feedback voltage with the difference between the reference voltage and the error correction voltage, and generates a comparison signal. The ON-time generator is configured to provide an ON-time signal. The logic circuit generates a logic control signal to control the power stage based on the comparison signal and the ON-time signal.
