Abstract
A switching converter having pulse skipping mode includes a power stage circuit, a feedback control circuit, an operating signal generator circuit and a pulse skipping circuit. The feedback control circuit generates an initial pulse width modulation (PWM) signal according the output power. The operating signal generator circuit masks a part of pulses of a clock signal according to a pulse width of a pulse skipping signal, so as to generate an adjusted PWM signal. The pulse skipping circuit adaptively generates a duty ratio signal according to an input voltage and an output voltage, so as to generate the pulse skipping reference signal related to a duty ratio of the initial PWM signal. The pulse skipping circuit compares an amplification signal with the pulse skipping reference signal to generate the pulse skipping signal. The power stage circuit converts the input power to the output power according to the adjusted PWM signal.
