用于提供混合式电压调节器的设备、系统和方法
摘要：
本公开示出了种混合式调节器拓扑结构,其能够更容易地被集成并且能够甚至利用小电感器维持在宽输出和输入电压范围上的高效率。所述混合式调节器拓扑结构能够包括两种类型的调节器:快速开关电感型调节器和将输入电压划分成输入电压的M/N分数的降压调节器。所述混合式调节器拓扑结构的所公开的实施例能够通过限制在快速开关电感型调节器中的开关上摇摆的电压来减少快速开关电感型调节器的电容性损耗。所述混合式调节器拓扑结构的所公开的实施例能够通过以高切换频率操作快速开关电感型调节器并且利用流过电感器的少量电流来减少快速开关电感型调节器的电阻器电阻性损耗。
摘要（英）：

The present disclosure shows a hybrid regulator topology that can be more easily integrated and that can maintain high efficiency across a wide output and input voltage range, even with a small inductor. The hybrid regulator topology can include two types of regulators: a flying switched-inductor regulator and a step-down regulator that divides the input voltage into an M/N fraction of the input voltage. The disclosed embodiments of the hybrid regulator topology can reduce the capacitive loss of the flying switched-inductor regulator by limiting the voltage swing across the switches in the flying switched-inductor regulator. The disclosed embodiments of the hybrid regulator topology can reduce the inductor resistive loss of the flying switched-inductor regulator by operating the flying switched-inductor regulator at a high switching frequency and with a small amount of current flow through the inductor.
