  • Abstract
    To improve efficiency over a wide load range, it is important to dynamically adjust the operational phase number in multiphase voltage regulators. This paper analyzes in detail the power loss profile of a synchronous multi-phase buck converter and defines the optimal phase number under different load conditions. Experimental results are provided to verify the theoretical results.
