MULTIPHASE DIGITAL CURRENT MODE CONTROLLER WITH DYNAMIC CURRENT ALLOCATION |
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. |
