数据: TPS6302x High Efficiency Single Inductor Buck-Boost Converter With 4-A Switches 数据表
TPS6302x器件为由两节或三节碱性电池供电的产品提供电源解决方案,NiCd或NiMH电池,或单节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3 A,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典型值4A。输出电压可使用外部电阻分压器进行编程,或者内部固定在芯片上。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。
TPS6302x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14引脚VSON封装,尺寸为3mm×4mm(DSJ)。
