LM3409: LM3409输出最低电压是多少

Part Number: LM3409

手册里面没有说明芯片输出的最低电压,我现在驱动一个LED,输出电压3.3V

LED无法工作,请问一下LM3409能不能输出3V的电压

  • 我需要以下波形以及输入/输出要求和开关频率:

    Inductor current
    Switch node voltage
    Input voltage
    Output voltage
    any other wave forms that provide me information on the issue that is occurring

    你的波形应该与我下面发布的波形相似。这是TPS92682EVM的波形

  •  绿色是Coff引脚电平,黄色是Pgate引脚电平,驱动PMOS得电平没有保持住,

     原理图这样得,现在EN引脚直接接的VCC

  • 你能把我要求的信息发过来吗?我真的需要它来帮助你。..
    我会说,看起来你的转换器退出了,但老实说,我无法知道
