• Problem with ADP5024

    Hi,

    I have designed a PCB with Altera Cyclone IV GX FPGA, ADI's AD7626 ADC and some other components. I used ADP5024 regulator for powering the FPGA. I followed the recommendations given by the following document:

  • What is the difference between ADP5024ACPZ-R2 and ADP5024ACPZ-R7?

    The ADP5024 datasheet lists these variants but shows nothing different between the two.

  • Power Up Sequencing using Enable Pin

    Hi

    For our application we want to use yours ADP5024 and generate delay Between BUCK1 and BUCK2 Enable pin's.

    As mentioned in the data sheet those pins are active logic level high  with Vih of min 1.1v.

    Your ADP5134 has the feature of precision enable…

    checked that the fb resistors are correct.

  • ADP5024无输出

    我们正在开发一款手持设备用到了ADP5024芯片,现在碰到的现象是上电之后芯片好像就进入到低输入电压锁定状态,BUCK输出对地基本上能测到内部的PULL-DOWN电阻,等VIN放电结束后VOUT对地电阻又恢复高阻状态。  

    DATASHEET来看,即使UVLO保护后,当VIN达到UVLO以上输出应该恢复正常才对。更何况我们的VIN上电波形是很好的上升波形,好像不应该会锁定才对。

    另外Table 2里的UVLOvin1rise   UVLOvin1fall   UVLOvin1rise   UVLOvin1fall…

  • ADP5024: How to connect an unused Buck regulator

    Hello,

    I was unable to find an answer to this in the datasheet... how should I connect the following ADP5024 pins if I do not want to use the second Buck regulator?

    VIN2, VOUT2, SW2, FB2, PGND2

    Obviously EN2 will be connected to ground in this case…

  • RE: 关于ADP5024的问题

    update:重新设计了一块专用于测试电源的板子,又发现了一些别的问题。首先,电源有输出了,但是所有的输出均不正确。其中两路DC输出均为固定电压值越1V(0.99V-1.01V),不论是否接FB电阻。而LDO输出为电源电压,接了FB电阻。虽然比完全没有输出要好一些,但是现在这输出也完全没法用,请教各位!!
