• LTM8003 shows higher H-field radiation then regular syncronous buck converter

    Hi ADI experts,

    I built a near-field radiation probe using an oscilloscope probe and a ground spring, as shown in the figure below.

    With this home-made H-field probe, I measured the radiation of LTM8003, which is a buck micro-module with Silient Switcher…

  • LTM8003 run/shutdown problem

    Hey

    I am using in my design in LTM8003HY.

    The pin of the RUN is connected with pull-down to the ground , To active the run pin i need to bring 3.3V form another card.

    The LTM8003HY get 28V to the Vin.

    Vout is design to supply 12V , and the BIAS pin connected…

  • What's the difference between LTM8003 and LTM8053?

    Hi,

    I'd like to know if there is any significant difference between LTM8003 and LTM8053, because I didn't find anything special.

    They share a similiar size and qualities, but have about a 1.5$ difference in favor of LTM8053.

    Best regards,

    Igal…

  • LTM8003HY as Negative topology external SYNC LEVELS

    Hi,

    If i want to use The LTM8003 to output -5V from 28V input as appeared at the typical application page

    and i need also to connect external SYNC clock,

    Should i take care for negative rails for this clock such as Vth_low = GND + 0.4V = -5 + 0.4 = -4.…

  • RE: LTM8005 - require some user guidance

    Hi Siglo,

    There is a typo. The part number is LTM8003. Sorry.

    In addition, I am confused with EMI features such as "low EMI", "Silent switcher", "Silent switcher 2" and "EN55022 Class B Certified". What are the differences among them? I think the scope…

  • 【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…
