说明

TPS561201 和 TPS561208 是采用 SOT-23 封装的简单易用型 1A 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 模式控制,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。

TPS561201 可在脉冲跳跃模式下运行,从而能在轻载运行期间保持高效率。TPS561201 和 TPS561208 可提供 6 引脚 1.6 × 2.9 (mm) SOT (DDC) 封装,额定结温范围为 –40°C 至 125°C。
