Claim 15:
16. A multi-phase switch mode power supply (SMPS) comprising:
a controller configured to output switching signals based on feedback from phases of the multi-phase SMPS, the feedback including a sensed current from each phase; and
a first driver configured to, based on the switching signals, generate driving signals to configure each of the phases to charge and discharge an inductor of the phase in order to generate a phase current, the first driver including:
a temperature sensing circuit configured to:
detect a temperature sensor directly coupled to the first driver, and
generate a digital temperature signal based on a temperature measurement made by the temperature sensor directly coupled to the first driver; and

phase-current sensors for each phase, the phase-current sensors adjusted by the digital temperature signal to temperature-compensate the sensed current from each phase coupled to the first driver.
