Abstract
A buck converter includes a switching circuit, an error amplifier, a comparator, a reset circuit, a logic gate, a flip-flop and a driver. The switching circuit generates an output voltage according to an input voltage. The error amplifier generates a compensation voltage signal according to a feedback voltage signal and the reference voltage signal. The feedback voltage signal is associated with the output voltage. The comparator generates a clock set signal according to the compensation voltage signal and a ramp voltage signal. The reset circuit generates a first reset signal according to an on-time control signal. The logic gate generates a second reset signal according to the clock set signal and the first reset signal. The flip-flop generates the on-time control signal according to the clock set signal and the second reset signal. The driver controls the switching circuit according to the on-time control signal.
