• LT8637 LTspice model

    Hello,

    I would like to know if there is a LTspice model for the LT8637 buck-converter part. In the current (updated July 2021) version of LTspice I could not find this part and it is also not available in the resources section at https://www.analog.com…

  • LT8637 with soft-start function

    Dears,

    We started to use the LT8637 recently and have obtained most of the time the desired results. The output noise remains below the 10mVpkpk as stated in the datasheet while the output voltage is generally stable. However, we have encountered some…

  • 【在线研讨会】Silent Switcher稳压器: 高效率、超低EMI

    在重视热耗散和效率的场合中,人们会用开关稳压器替代线性稳压器。开关稳压器通常是输入电源总线线路上的首个有源组件,因此对于整个转换器电路的 EMI 性能具有重大的影响。

    EMI发射有两类:传导和辐射。传导发射通过电线和走线连接到产品。辐射发射测试只有在设计基本完成之后才能正式进行。

    在近期的在线研讨会《Silent Switcher稳压器:高效率、超低EMI》中,从原理到封装到布局再到具体产品,重点介绍了大幅降低开关稳压器EMI辐射的新技术。

    首先,高频噪声来自哪里?在电子电路中,通过寄生电阻…
