摘要：
Methods and apparatus for workload balancing among power switching components in a multiphase switching power supply, the power supply including one set of power switching components for each switching phase, where workload balancing includes: dropping one or more switching phases when output current demand on the power supply drops below a predetermined threshold, leaving at least one active switching phase; and rotating the at least one active switching phase among all sets of power switching components.
