Optimizing design for low voltage DC-DC converters

The emerging portable battery-operated system demand compact, high efficiency, low-voltage and low-power DC-DC converters to maximize system run-time. Hybrid control strategy is used to achieve high efficiency and to select reasonable passive elements over a wide load range. The purpose of this paper is to study optimizing design for low-voltage DC-DC converters. In the paper, a hybrid-controlled buck converter is used to demonstrate the optimization.
