    • A current mode DC-DC controller operates with high efficiency even when the input and output voltages are close. Switches selectively connecting an input, ground and an output to inductor terminals are controlled in a buck/boost region to alternate between operation as a buck converter and operation as a boost converter. The number of switches repeatedly changing state is thus reduced, lowering switching losses and improving conversion efficiency. Current through the inductor during operation is sensed and compared to an error value to control switching from buck mode operation to boost mode operation and back.
    • 即使输入和输出电压接近,电流模式DC-DC控制器也能以高效率运行。 选择性地将输入,接地和输出连接到电感器端子的开关在降压/升压区域中被控制,以在作为降压转换器的操作和作为升压转换器的操作之间交替。 因此,重复改变状态的开关数量减少,降低开关损耗并提高转换效率。 在运行期间通过电感器的电流被感测并与误差值进行比较,以控制从降压模式操作到升压模式操作和返回的切换。
