数据： TPS6240x-Q1 2.25-MHz 400-mA and 600-mA Dual Step-Down Converter 数据表
TPS6240x-Q1系列器件是同步双路降压DC-DC转换器，针对电池供电的便携式应用和汽车系统进行了优化。它们提供两个独立的输出电压轨，由可充电电池或标准3.3V或5V电压轨供电。
EasyScale™串行接口允许在运行期间修改输出电压。固定输出电压版本TPS62402-Q1，TPS62404-Q1和TPS62405-Q1支持单引脚控制的简单动态电压调节，适用于低功耗处理器。
TPS6240x-Q1工作在2.25 -MHz固定开关频率，在轻负载电流下进入省电模式，在整个负载电流范围内保持高效率。对于低噪声应用，可以通过将MODE /DATA引脚拉高来强制器件进入固定频率PWM模式。关断模式可将电流消耗降至1.2μA（典型值）。这些器件允许使用小型电感器和电容器来实现小尺寸解决方案。
