摘要：
A single-inductor multiple-output (SIMO) DC-DC converter providing buck and boost outputs with a new control topology is presented. In the proposed switching sequence, which does not require any special blocks, energy delivery is always accomplished by flowing energy through an inductor, which leads to high conversion efficiency regardless of the balance between the buck and boost output loads. Implemented in 0.35-mu m CMOS, the proposed SIMO DC-DC converter achieves high conversion efficiency regardless of the load balance between the outputs. The measured maximum efficiency reaches 82% under heavy loads.
