Dear Sir/ Madam,
Kindly review the enclosed schematic and let me know if any changes are required.
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…
this looks nearly the same (schematic and problem) that I am facing with an LTM4650. what was the fix here?
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…
what's meaning of diffp/diffn/diffout matching like this ? is the diffout float ok ?
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…
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。
Dear dkb,
Thank you for your reply.
But I have some questions about your answers.
Actually my customer's request get similar values both a result value of bode plot and stability value of Loop comp tap in LTPower Cad.
This is for using DCDC modeling…
