Abstract | A multi-phase control circuit and a temperature balance control method thereof The temperature balance control method of the multi-phase control circuit includes the steps of: acquiring a first temperature signal reflecting a representative temperature among a plurality of power stages, then acquiring a plurality of second temperature signals reflecting a respective temperature of each of the plurality of power stages; and adjusting a pulse width and/or frequency of a pulse width modulation signal of at least one of the plurality of power stages according to a comparison result between the first temperature signal and the second temperature signal so as to balance the temperatures of the plurality of power stages. |
