摘要： A control circuit of a DC/DC converter, wherein the DC/DC converter further comprises a high-side switch and a low-side switch, and wherein the DC/DC converter provides an output signal to a load. The control circuit comprises: an amplifier configured to receive a feedback signal and a reference signal to provide an error signal; a ramp generator configured to provide a ramp signal; a comparator configured to receive the ramp signal and the error signal to provide a comparison signal; and a COT generator configured to receive the comparison signal, to provide a COT signal to control the high-side switch and the low-side switch.
