TPS62420器件是一款同步双路降压DC-DC转换器，专为电池供电的便携式应用而优化。它提供两个独立的输出电压轨，由1节锂离子电池或3芯镍氢/镍电池供电。该器件也适用于标准的3.3V或5V电压轨。
使用EasyScale串行接口，可在运行期间修改输出电压。因此，它支持低功耗DSP和处理器的动态电压调节。
TPS62420工作在2.25MHz固定开关频率，并在轻负载电流下进入省电模式工作，以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。在关断模式下，电流消耗降至1.2μA。该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。
TPS62420采用10引脚无引脚封装（3mm x 3mm QFN）。
