• LT8616 Voltage in VOUT1 is unable to regulate to 5V and outputs 11V; power good 0V for VOUT1

    Hello,

    I have used LT8616 in my recent project and expected everything to work fine but the chip outputs 11V instead of 5V. This fired almost the entire system.

    Input 12V,

    Output 1: 5V(expected) 11V (actual) Output 2 :3V3

    PG 1 : 0V PG2: 3V

    I will attach…

  • LT8616 Simulation at low current load not plausible

    Hello
    I want to use the LT8616 dc/dc-converter to power my application circuit.
    The application needs a 3.3V and a 5V power supply, with an input voltage between 20V and 38V.
    The normal load current is between 75mA und 800mA.
    I went through the data…
  • RE: Design Parameters for LT3506

    Hello,

    in your scenario I would use a different for two reasons:
    1. We have synchronous (more efficient+space saving) dual buck regulators in our portfolio.

    2. More than that the LT3506 won't work under all conditions, as he needs more Vin to start than…

  • RE: Does the LT8614 come multiple output channels? Is there micromodule option with LT8614?

    On behalf of Anthony Armstrong: 
    The LT8614 is a Single Output step-down converter which can deliver up to 4A of continuous output current. We currently have four 42V input capable dual output devices: the LT8653S with dual 2A per channel, the LT8650S with…

  • 【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…
