• ADP5024 output problem

    Hello, I am having an issue with the switching outputs on a new board with ADP5024.

    Expected:

    VOUT2 =1.8V

    SW2 switches from 0~5V (VSYS) at 36% duty cycle, at 3MHz.

    Actual:

    VOUT1 ~100mV

    SW2 switches from -1~4.5V at 20% duty cycle, at 1.5MHz

    My schematic…

  • 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:

  • 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…

  • 关于ADP5024的问题

    最近在做ADSP BF707的板子,参考官方开发板ADSP-BF707 EZ-Board的电源设计采用ADP5024为BF707供电。但是我这几天测试发现ADP5024上电后没有输出(三路都没有,其中两路DC一路LDO),使用示波器观察,SW、VOUT、FB以及LDO的输出均没有波形和电压(简单的说就是这块芯片上电没上电都没输出,就是完全没有工作),芯片的使能也都接高电平(5V)了。我焊了两块板子,都没有带负载,都没有工作。请问是否有人遇到了相同的情况,可能是什么原因导致的,还是我哪边出了问题,求解…

  • 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…

  • 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…
