数据： TPS6122x Low Input Voltage, 0.7V Boost Converter With 5.5μA Quiescent Current 数据表
TPS6122x系列器件为由单节电池，两节电池或三节电池供电的产品提供电源解决方案，NiCd或NiMH，或单节锂离子或锂聚合物电池。可能的输出电流取决于输入 - 输出电压比。升压转换器基于使用同步整流的迟滞控制器拓扑，以在最小静态电流下获得最大效率。可调版本的输出电压可通过外部电阻分压器进行编程，或在内部设置为固定输出电压。可通过特色使能引脚关闭转换器。在关闭时，电池消耗最小化。该器件采用6引脚SC-70封装（DCK），尺寸为2 mm×2 mm，可实现小型电路布局尺寸。
