描述

TPS6208x器件是高频同步降压转换器系列产品。该器件的输入电压范围为2.3V至6V，支持常用电池技术。此外，该器件可用于低电压系统电源轨。

TPS6208x专注于在宽输出电流范围下实现高效降压转换。该转换器在中等程度的负载到高负载时运行于脉宽调制（ PWM）模式，并在轻负载电流条件下自动进入省电模式运行，从而在整个负载电流范围内保持高效率。为了在超低负载或无负载电流下保持高效率运行，该器件采用具有超低静态电流的贪睡模式。该功能通过MODE引脚使能，可延长增加电池驱动应用的运行时间，同时保持最低待机电流，以满足针对低待机电流的绿色能源标准。

为了满足系统电源轨需求，内部补偿电路支持使用高于100μF的外部输出电容。凭借DCS-Control架构，可实现出色的负载瞬态性能和输出电压调节精度。该器件采用带有散热焊盘的2mm x 2mm WSON封装。
