摘要： A switching regulator includes a controller and a power stage for coupling to a load through an inductor and a capacitor. The a controller is operable to control operation of the power stage via a pulse width modulation (PWM) signal generated based on a difference between a reference voltage and the load voltage and sample the inductor current at a lower rate than the load voltage. The controller is further operable to estimate the capacitor current based on the sampled load voltage, generate an offset to the reference voltage based on the sampled inductor current and the estimated capacitor current and adjust the PWM signal applied to the power stage based on the offset. The switching regulator can be single-phase or multi-phase.

摘要： Disclosed is a digital current sharing structure and method in which a plurality of regulators are configured to share the load current. Current share circuits in each of the regulators are configured to measure and compare the average current provided by that particular regulator with the overall average current provided by all the regulators. Each of the current share circuits then provides an output so that the output of each regulator is adjusted to provide the same amount of current to the load. Digital processing with both analog and digital averaging are disclosed. Also disclosed is a programmable hysteresis technique to eliminate relatively trivial adjustments.

摘要： A multiphase switching regulator includes a power stage with at least a first phase and a second phase for supplying power to a load through inductors coupling the phases to the load. The multiphase switching regulator is operated by switching the first phase at a higher switching frequency than the second phase via pulse width modulation (PWM) signals provided to the phases. A phase-specific target current is generated for each phase at the switching frequency for that phase based on the difference between an output voltage of the power stage and a reference voltage. The current in the inductors coupling the phases to the load is sensed, and a duty cycle of the PWM signal provided to each phase is adjusted based on the phase-specific target current and sensed inductor current for that phase.
