一种具有完全集成电流平衡方案的多相同步Buck变换器

A multiphase synchronous buck converter has been developed, in which the number of switching phases is determined by the sensed average load current. The maximum number of switching phases is four. The dc resistance (DCR) of switching inductor is used to detect the average current, which is also utilized to balance the load current among the multiple switching phases. The instantaneous inductor cu...
