Abstract
A feedback control circuit of a pulse-frequency modulation (PFM) converter includes an on-time timer circuit and a detection circuit. The on-time timer circuit generates an on-time control signal for controlling an on-time duration of a switch circuit included in a power stage circuit of the PFM converter. The detection circuit controls the on-time timer circuit to adaptively adjust the on-time control signal according to a pulse interval between two successive inductor current pulses of the PFM converter.
