Abstract
A multi-rail switching converter providing a plurality of output voltages has a master switching circuit, a plurality of slave switching circuits and a control circuit. The control circuit has an interleaving control circuit, the interleaving control circuit judges a phase zone of a corresponding slave switching circuit based on a switching control signal of the master switching circuit and a set signal of the corresponding slave switching circuit, and adjusts a turn-ON moment of the corresponding slave switching circuit based on the phase zone of the corresponding slave switching circuit.
