• LTM8047 not working: output ~38V

    Hi, 

    I am testing multiple LTM8047 that is connected to a digital potentiometer. This is the circuit used: 

    The ADJ pin is connected to a digital pot varying the resistance between 10k and 21k . But the output is always ~38v . This is true for multiple…

  • LTM8047 isolated gate drive power supply

    I am using the LTM8047 for a low side isolated gate drive power supply. I am also using it for a high side isolated gate drive power supply.

    what is the CMTI rating of this PS?

    I am having an issue, as I increase the input line voltage in my inverter…

    • 这个是不是LTM8047最初的设计缺陷;
    • 这个设计缺陷,是不是需要在输出端并联一个电阻才能彻底解决;
    • 另外输出并联一个电阻就能解决这个问题,为什么不在LTM8047的数据手册里体现,因为不是每个电路设计工作者,会下载芯片所有的参考手册来参考毕竟时间有限(多么恐怖啊,为解决这个问题我花了一周多时间,因为咨询了官网代理商的技术支持也没有得以解决);
    • 如果真有设计缺陷,希望更新到官网LTM8047的数据手册。

    希望,能回复fulaer@sina.com。
