Abstract
Methods and systems for performing current sense compensation for one or more power stages in a multiphase voltage regulator are described. A controller can be connected to a plurality of power stages through a communication interface. The controller can generate a data packet including a command to obtain temperature information and an address that identifies a specific power stage among the plurality of power stages. The controller can send the data packet to the plurality of power stages using the communication interface. The controller can receive temperature information of the specific power stage from the specific power stage through the communication interface. The controller can compensate a sensed current of the specific power stage based on the received temperature information of the specific power stage.
