• 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…

  • RE: power umodule

    HI Clt,

    You may opt to use LTM8003 instead.

    The input and output voltages are within the range of the part and it is able to operate at higher output current.

    The voltage drop when the battery is nearly depleted should not affect the output current, as…

  • 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…
