具有集成铁氧体磁珠滤波补偿的 17V 输入电压、3A 低噪声、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 10µVRMS 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进 • 低输出 1/f 噪声 RMS （100Hz 至 100kHz）\n• 大于 65dB 的高 PSRR（高达 100kHz）\n• 可与外部时钟同步（可选）\n• 展频调制（可选）\n• 0.8V 至 5.5V 输出电压范围\n• 输出电压精度为 ±1%\n• 用户定义的欠压锁定\n• 可调节软启动\n• 输出放电（可选）\n• -ET 版本为 –55°C 至 125°C\n• 使用 TPSM8291x 并借助 WEBENCH Power Designer 创建定制设计;
