数据: 具有 DCS-Control™ 的 TPS6216x 3V 至 17V 1A 降压转换器 数据表 (Rev. E)
TPS6216x系列是一款简单易用的同步降压DC-DC转换器,针对高功率密度的应用进行了优化。该系列器件的<关键字典型值高达2.25MHz 3V至17V,非常适用于由锂离子或其他电池以及12V中间电源轨供电的系统。该器件的输出电压为0.9V至6V,支持高达1A的持续输出电流(使用100%占空比模式)。
此外,还可以通过配置使能引脚和开漏电源正常状态引脚实现电源排序。
在节能模式下,器件可根据输入电压(VIN)生成约17μA的静态电流。负载较小时可自动且无缝进入节能模式,同时该模式可保持整个负载范围内的高效率。该器件在关断模式下处于关断状态,期间的流耗低于2μA
此器件具有可调节输出电压和固定输出电压版本,采用2.00mm x 2.00mm 8引脚WSON封装(DSG)或3.00mm x 3.00mm 8引脚VSSOP封装(DGK)。
