  • LTM4630输出震荡

    我是按照手册中图24给的连接方法,对LTM4630两个通道进行并联输出,实现0.9V 36A的一个设计。具体见下图。

    其中INTVcc上并联对地的电容后来改成了2.2uF,且该引脚工作时电压正常为 5V。输出的 FPGA_0V9D2 还对地并联有 3 个 220uF 的贴片铝电解电容,还有若干 0.01uF-22uF 的陶瓷电容。Vaux_5V 是通过另外一个开关电路得到,工作正常。目前发现的问题是,Vin 加电 7V ,当输出电压逐渐达到 0.9V 之后就开始大幅震荡,最大超过2V。此时因为电压增高…

  • Unstable output of LTM4630

    I designed a 0.9V 36A power circuit for my FPGA using LTM4630. The design refered to the circuit given in Figure 24 of the datasheet. The detail is given in the following figure.

    where C115 is 2.2uf instead, and the voltage of INTVcc is normally 5V…

  • about INTVCC of LTM4630?

    hello,

    Recently I make LTM4630 to output 1V to FPGA VCCINT for 18A.During my design,I find a question about INTVCC with different connect between LTM4630fa datasheet and DS2081-a as following:

    the datgasheet tells that INTVCC should connect PGND ,but…

  • Power output of LTM4630-1

    Hi,

    I am using LTM4630-1 In my Design and it is set to give 0.95V as output.

    I checked Run voltage it is 1.6V and INTVCC it is 5V.

    But output of the LTM4630-1 is not 0.95V it is giving 5V.

    What might be the issue? Help me resolving the issue.

    Regards…

  • LTM4630电源模块在多路并联时在pcb设计时需要注意那些细节

    LTM4630电源模块在多路并联时在pcb设计时需要注意那些细节

    比如在3路或者4路并联时在画pcb时走线需要注意那些地方,要加入对称设计和阻抗匹配吗,

    如何才能做到并联均流效果最好,

    请大家提出一些建议和指导,谢谢。

  • RE: 一图解析 ADI 电源产品的发展趋势

    LTM4630 是一款双输出 18A 或单输出 36A 输出开关模式降压型 DC/DC μModuleRegistered (微型模块) 稳压器。封装中内置了开关控制器、功率 FET、电感器和所有的支持组件。LTM4630 可在一个 4.5V 至 15V 的输入电压范围内运作,支持两个输出电压范围均为 0.6V 至 1.8V (各由单个外部电阻器来设定) 的输出。该器件的高效率设计能够为每个输出提供 18A 的连续电流。仅需少量的输入和输出电容器。LTM4630 的引脚与 LTM4620 和 LTM4620A (双输出…

  • RE: LTM4637 negative output

    The maximum input voltage is 18V of LTM4630, so I don't think it is suitable for 12V input & -5V output(20A). In this case, I think it would be better to use two LTM4638 than two LTM4637, because LTM4638 is cheaper than LTM4637. Am I right ?
