• ADP2325 Problems

    Hi Guys

    We are struggling with a design containing an ADP2325 buck converter that will be used to generate a 1V for an FPGA.

    (It would be the first time using this part)

    Here are some of the relevant values:

    • 5V input
    • 1V output (Parallel Buck…
  • Design with ADP2325

    Hello,

     

    My name is Meir and I am DFAE at Phoenix technologies in Israel.

     

    Silicom, one of my customers, started to evaluate the ADP2325 and ADP5023.

    They are using the ADIsimPOWER and we have some questions regarding the results that we have got…

    Hi!

    We have a problem with calculation of design containing an ADP2325 Step-Down Regulator.

    Here are some of the our values:

    1. Vin = 15 V;
    2. Vout = 3,3 V;
    3. Fsw = 300 kHz;
    4. Iout = 1 A;

  • ADP2325输出电容怎么选择

           我在最近一次的电路设计中使用ADP2325给FPGA供电,仔细看了ADP2325的PDF后输出电容的选择仍然有诸多不明白之处。恳请指导。

        电源输入输出要求入文件“ADP2325_cn.pdf”第24页的设计示例所示

    问题1:在设计工具中蓝色下划线处的两个参数应该怎么设置。

    问题2:文件“ADP2325_cn.pdf”第25页中计算输出电容公式中下划线处的参数值,在该例中是怎么计算的,是多少。

    问题3:文件“ADP2325_cn.pdf第23页中,计算补偿点电路公式中,蓝色下划线处的两个参数的值是多少…

  • ADP2325输出异常,不能正常使用

    我用ADP2325做电源设计,输入“+12V”,输出 "+5V"。稍不注意,在无负载的情况下,输出就会变为“+12V”;若有负载,在用直流电源供电的强狂下,会把直流电源的电压拉下来。我不清楚是ADP2325坏了,还是FDMS7578坏了;但同时更换这两个片子就能正常输出“+5V”。这个设计太脆弱,求指教,这里哪里设计不合理,谢谢!

  • RE: ADP2323ACPZ ripples at output

    Dear Ryang , 

    We are using ADP2323, the schematic remains the same as mentioned previously , However there are two capacitors connected at three connectors viz JX1,JX2 & JX3 on which PicoZed board will be connected  , please refer the image attached…

  • RE: Looking for power...

    Dim,

    let's start with the LDOs, which I assume you are running them from the 5V rail.

    You could consider the ADP222 (dual 300mA) or the ADP323 (tripple 200mA).

    The Linear Regulator design tool will help you with determine if these devices will…
