TPS6209x器件是一款高效同步降压转换器,此转换器针对小外形尺寸,高效应用进行了优化并适合于电池供电类应用。为了最大限度地提升效率,此转换器运行在2.8 MHz /1.4 MHz的标称开关频率的脉宽调制(PWM)模式下并在轻负载时自动进入省电运行模式。当被用于分布式电源和负载点调制时,此器件允许到其它电源轨的电压跟踪并且耐受范围在10μF到高达150μF甚至更高的输出电容。通过使用DCS™控制技术,此器件可实现出色的负载静态性能以及精确的输出电压调制。
此输出电压启动斜波由软启动引脚控制,从而使器件可作为独立电源运行或运行在跟踪配置下。通过配置使能和开漏电源正常引脚也有可能实现电源排序。在省电模式下,此器件运行在典型值为20μA静态电流下。在全部负载电流范围内,自动进入省电式并且无缝保持高效。
