Abstract
A conversion control circuit for controlling a stackable multiphase power converter, wherein the stackable multiphase power converter includes plural stackable sub-converters, each of which includes a power stage circuit and a conversion control circuit. The conversion control circuit includes: a synchronization terminal, through which a synchronization signal is transmitted and received among the plurality of synchronization terminals of the plural conversion control circuits; and a fault indication signal or status, where plural pulses of the synchronization signal have a fault indication status. When at least one of the plural stackable sub-converters experiences a fault, the fault indication signal or status indicates and controls the conversion control circuit to enter a fault operation. The fault operation includes: the fault indication signal or the fault indication status disables a faulty one of the plural stackable sub-converters, and one of the non-faulty ones among the plural stackable sub-converters takes over.
