description Current sensing in switching power converters. At least one example is a method comprising: discharging an inductor of a buck converter using a low-side FET during a discharge mode of a first cycle; providing, during the discharge mode, a signal indicative of instantaneous current to a voltage regulator, the signal indicative of instantaneous current proportional to current through the inductor during at least a portion of the discharge mode; charging the inductor using a high-side FET during a charge mode, the charge mode in a second cycle subsequent to the discharge mode; and providing, during the charge mode, an emulated signal to the voltage regulator, the emulated signal generated based on the current through the inductor in the discharge mode.
