ABSTRACT:
A constant on-time regulator that may use a capacitor with low ESR without needing a series resistor is provided. A capacitor is employed to AC-couple a current sense voltage into the reference signal to provide a modified reference signal. The comparator compares the feedback voltage with the modified reference signal rather than a constant reference signal. Also, a switch may be included between the current sense voltage and the reference signal to improve load regulation.
