一种用于LED应用的带自适应参考电感电流控制的单电感多输出升压变换器

This study proposes a single-inductor multiple-output (SIMO) converter with an adaptive reference inductor current (ARIC) control for low-power light-emitting diode (LED) applications. Owing to the benefits of the SIMO architecture, component counts and circuit size can be reduced significantly. The ARIC control method inserts a freewheeling duration into every switching cycle to suppress cross-regulation issues among multiple outputs, while dynamically adjusting the freewheeling level of the inductor current based on load conditions to maintain high efficiency across the entire output range.
