Abstract: In a DC-DC converter, a duty-cycle control signal is generated in response to comparing the switching stage output voltage and a reference voltage signal. A first circuit compares the duty-cycle control signal and a ramp to produce a PWM signal. A second circuit compares the duty-cycle control signal and a skip threshold to produce a skip control signal which halts switching operation of the switching stage. A count is made of number of periods of the skip control signal during a monitoring time window and the number of periods of a clock signal during a period of the skip control signal is counted. When the counted number of skip control signal periods is within a first range and the counted number of clock signal periods is within a second range, a common detection signal is asserted to trigger varying a value of the skip threshold signal.
