Abstract：
 This invention relates to a multiphase switching power supply which adopts master-slave current equational MPU. It belongs to computer device technology field. It contains voltage unit which is used to receive PWM signal and input voltage and output inductive current; error amplifier which is used to correct the output voltage; current selector which is used to select reference current; in the current selector the first method of selecting current is used to send n input inductive current in order to current data bus and the second method of selecting current is used to send the maxima of these inductive current to current data bus; current amplifier which is used to filter and amplify the current error and finish the transaction from current signal to voltage signal and add to voltage error; comparator which is used to compare the total voltage error and saw tooth wave and output PWM signal. This invention's multiphase switching power supply supplies two master-slave current selecting methods. It effectively ensures every phase of inductive current to be in balance.
