数据： TPS6303x High Efficiency Single Inductor Buck-Boost Converter With 1-A Switches 数据表
TPS6303x器件为由两节或三节碱性电池，镍氢电池或镍氢电池供电的产品提供电源解决方案，电池锂离子或锂聚合物电池。使用单节锂离子或锂聚合物电池时，输出电流可高达600 mA，并将其放电至2.5 V或更低。降压 - 升压转换器基于固定频率，脉冲宽度调制（PWM）控制器，使用同步整流来获得最大效率。在低负载电流时，转换器进入省电模式，以在宽负载电流范围内保持高效率。可以禁用省电模式，强制转换器以固定的开关频率运行。开关中的最大平均电流限制为1000 mA的典型值。输出电压可使用外部电阻分压器进行编程，或在芯片内部固定。可以禁用转换器以最大限度地减少电池消耗。在关机期间，负载与电池断开连接。
TPS6303x器件可在-40°C至85°C的自由空气温度范围内工作。这些器件采用10引脚VSON封装，尺寸为2.5 mm×2.5 mm（DSK）。
