17V 输入电压、3A 低噪声和低纹波降压模块

TPSM8291x 器件是一系列高效、低噪声和低纹波电流模式同步降压电源模块。这些器件非常适合通常使用 LDO 实现后置稳压的噪声敏感型应用，例如高速 ADC、时钟和抖动清除器、串行器、解串器和雷达应用。\n\n这些器件在 2.2MHz 或 1MHz 的固定开关频率下工作，并可与外部时钟同步。\n\n为了进一步减小输出电压纹波，器件集成了环路补偿，可与可选的第二级铁氧体磁珠 L-C 滤波器一起工作。该功能可将输出电压纹波降至 10µV RMS 以下。\n\n通过使用 NR/SS 引脚上的集成电容器对内部电压基准进行滤波来实现类似于低噪声 LDO 的低频噪声水平。可以在模块中添加一个外部电容器以 • 低输出噪声 \n• 电源正常状态输出\n• -40°C 至 125°C 的结温范围 \n• 使用 TPSM8291x 并借助 WEBENCH Power Designer 创建定制设计;
