• Power output of LTM4630-1


    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.

  • 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?


    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…

  • 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…
