Multi-phase boost converter with phase self-detection and detecting circuit thereof
A multi-phase boost converter with phase self-detection and a detecting circuit thereof are provided. The multi-phase boost converter comprises M switching circuits, a capacitor, a control circuit and a detecting circuit. Each switching circuit has an input end and an output end. N inductors are coupled in parallel between the input ends and an input voltage. The output ends are coupled to an output voltage. The control circuit controls the conduction status of the switching circuits according to a feedback voltage corresponding to the output voltage. The detecting circuit coupled between the input ends and the control circuit detects the conduction status between the input voltage and each of the input ends, for outputting a first control signal. The control circuit controlled by the first control signal selectively controls at least one of the switching circuits. N is a positive integer less than or equal to M.
