数据: TPS6216x-Q1 3-V to 17-V 1-A Step-Down Converter with DCS-Control™ 数据表
TPS6216x-Q1是易于使用的同步降压DC-DC转换器,专为高功率密度应用而优化。高开关频率(典型值为2.25 MHz)允许使用小型电感器,并通过利用DCS-Control™拓扑结构提供快速瞬态响应和高输出电压精度。
具有宽工作输入电压范围该器件的电压为3 V至17 V,非常适合采用锂离子电池或其他电池以及12 V中间电源轨供电的系统。它在0.9 V和6 V输出电压(100%占空比模式)下支持高达1A的连续输出电流。
通过配置使能和漏极开路电源良好,也可以实现电源排序引脚。
在省电模式下,器件从VIN吸收约17μA的静态电流。省电模式,在负载较小时自动无缝输入,在整个负载范围内保持高效率。在关断模式下,器件关闭,关断电流消耗小于2μA。
器件提供可调和固定输出电压版本,采用8引脚WSON封装,尺寸为2× 2毫米(DSG)。
