数据： TPS62136, TPS621361 1-MHz High Accuracy 3-V to 17-V 4-A Step-Down Converters with DCS ControlTM 数据表
TPS62136和TPS621361是基于DCS-Control™拓扑的高效且易于使用的同步降压DC-DC转换器。器件宽输入电压范围为3 V至17 V，适用于多节锂离子电池以及12 V中间电源轨。这些器件提供4A连续输出电流。 TPS62136在轻负载时自动进入省电模式，以在整个负载范围内保持高效率。有了这个，该设备非常适合需要连接待机性能的应用，如超低功耗计算机。将MODE引脚设置为tolow后，器件的开关频率将根据输入和输出电压自动调整。该技术称为自动效率增强（AEE™），并在整个操作范围内保持高转换效率。它在PWM模式下提供1％的输出电压精度，因此可以设计具有高输出电压精度的电源。
该器件的典型静态电流为18μA。在关断模式下，电流通常为1μA，TPS62136的输出有效放电，而TPS621361的输出电压放电功能无效。
TPS62136可调节版本，采用3 mm x 2封装-mm VQFNpackage。
