该论文提出了一种双降压双输出转换器，基于PD 3.1标准实现从48V输入的高效电压转换，通过改进的电流平衡技术将交叉调节降低至0.025mV/mA，解决了多输出电源管理中的交叉干扰和电流不平衡问题。

Due to the usage of high voltage switches, the need for small font factor and multiple outputs for high power density power management becomes imperative in Internet-of-Things (IoT) electronics. Thus, single-inductor dual-output (SIDO) converters (top left of Fig. 11.4.1) become one of the best candidates due to its dual outputs with the use of a single inductor [1–3]. However, the bulky inductor determined by the maximum current driving capability is not efficient at light loads. In addition, SIDO converters also suffer from large output voltage ripple
