The invention relates to a multi-phase power supply regulator and a temperature balance control method thereof, and discloses a temperature balance control method in the multi-phase power supply regulator, comprising: providing a multi-phase power supply regulator, the multi-phase power supply regulator comprising a controller and a plurality of power stages, the controller transmits a plurality of corresponding control signals to the power stages respectively, each power stage comprises a temperature sampling unit, and a plurality of output ends of the temperature sampling units are connected in parallel and output a temperature detection signal. By sequentially adjusting the control signal of each power level and detecting the change condition of the temperature detection signal, the higher temperature in each power level is judged, and the temperature of the power level is reduced, so that the temperature of the multi-phase power supply regulator is distributed in a balanced manner.
Description
technical field [0001] The present invention relates to a voltage regulator, and more particularly, to a multiphase power regulator and a temperature balance control method thereof. Background technique [0002] With the continuous development of semiconductor technology, such as computers and peripheral digital products are increasingly updated. In the application integrated circuits of computers and peripheral digital products, due to the rapid development of semiconductor technology, resulting in more diversified requirements for integrated circuit power supplies, various combinations of voltage regulators such as boosters and step-down devices are used to achieve The different power requirements of various integrated circuits have also become one of the important factors for the ability to provide a variety of diversified digital products. [0003] Among various voltage regulation circuits, multiphase power regulators have good performance in high current or high power ...
