Abstract:
Systems and methods for individual phase temperature monitoring and balance control in a multi-phase voltage regulator may include a plurality of smart power stages including a first smart power stage and a second smart power stage and a voltage regulator controller. The voltage regulator controller may send a first control signal to the first smart power stage to enable the first smart power stage to send a first temperature of the first smart power stage to the voltage regulator controller during a first phase of a switching cycle. The voltage regulator controller may also determine that the first temperature received by the voltage regulator controller corresponds to the first smart power stage based on the first control signal. The voltage regulator controller may further send a second control signal to the second smart power stage to enable the second smart power stage to send a second temperature to the voltage regulator controller during a second phase.
