说明

TPS562200 和 TPS563200 是采用 6 引脚 SOT-23 封装的简单易用型 2A 和 3A 同步降压转换器。

此器件被优化为使用尽可能少的外部组件即可运行,并且可以实现低待机电流。

这些开关模式电源 (SMPS) 器件采用 D-CAP2 控制拓扑,从而提供快速瞬态响应,并且在无需外部补偿组件的情况下支持专用聚合物等低等效串联电阻 (ESR) 输出电容器以及超低 ESR 陶瓷电容器。

TPS562200 和 TPS563200 可在高级 Eco-mode 下运行,从而能在轻载运行期间保持高效率。这些器件采用 6 引脚 1.6mm × 2.9mm SOT (DDC) 封装,额定工作环境温度范围为 –40°C 至 85°C。
