Abstract
A fault detection method for a multiphase switching converter with a plurality of switching circuits. The fault detection method includes the following steps. 1) Generate a comparing signal by comparing a corresponding current reference signal with a corresponding current sensing signal indicative of a current flowing through a corresponding switching circuit. 2) Generate a duration detecting signal by detecting the duration of the corresponding comparing signal keeping in a first state. 3) Generate a first mode signal indicating whether the corresponding switching circuit is under power operation and a second mode signal indicating whether the corresponding switching circuit works in DCM or CCM. And 4) generate a fault signal indicating whether the corresponding switching circuit is in a fault condition based on the corresponding duration detecting signal, the corresponding first mode signal and the corresponding second mode signal.
