移动产品的每年性能和功能密度的每年提高促进了对具有更高容量的电池的需求，从而促进了更高的电力交付解决方案，以维持明智的充电时间。开发了USB-C电力传递规范，以满足这些更高的需求，通过在较高的设置中启用输入电源VBUS电压，例如9V，以允许更高的功率传递，最大100W USB-C电缆。为了弥合从此输入电压到一个两电池电池产品充电的差距，需要一个功率和空间效率的DC-DC转换器。
The annual increase in performance and feature density of mobile products has driven the need for batteries with higher capacity and thus higher power-delivery solutions to maintain sensible charging times. The USB-C power-delivery specification was developed to meet these higher demands by enabling the input supply VBUS voltage at a higher setting, e.g., 9V, to allow higher power delivery, up to 100W, while minimizing current levels and associated IR drops across the USB-C cable. To bridge the increased gap from this input voltage to charge one-and two-cell battery products, a power-and space-efficient DC-DC converter is desirable.
