Original Abstract Submitted
a circuit for slew rate detection and phase control in a multi-phase converter is provided. the circuit includes a first comparator configured to trigger when an output voltage of the multi-phase converter falls to a first output voltage level threshold value. the circuit further includes a second comparator configured to trigger when the output voltage falls to a second output voltage level threshold value which is lower than the first output voltage level threshold value. the circuit further includes a timer configured to start to run for a predefined time window, when the output voltage of the multi-phase converter falls below first output voltage level threshold value. the circuit further includes phase control logic configured to distinguish the ramp rate of the output voltage of the multi-phase converter as corresponding to a slow-rate ramp, a mid-rate ramp or a fast-rate ramp based on the outputs of the first comparator, the second comparator and the timer and enable phases synchronously or asynchronously based on the distinguishing of the ramp rate of the output voltage of the multi-phase converter as corresponding to the mid-rate ramp or the fast-rate ramp.
