具有近阈值启动电压和高效率的自适应峰值电感电流控制PFM升压转换器

A high-efficiency boost dc–dc converter with adaptive peak-inductor-current (APIC) control method is proposed. Besides, a novel two-step startup procedure is also proposed and applied on the boost converter. The proposed integrated boost converter was fabricated by using a 0.18-μm 1P6M mixed-signal process with a die area of $\hbox{0.96 mm} \times \hbox{0.75 mm}$, and it is meant to be used with l...
