• ADP5070 has no negative voltage

    Hello,

    here is my design to have a look at. It was taken from an app note 1:1. Little diff. for the Output voltages, but no Focus here. I do not get any negative voltage out of this device. The upper Regulator works best! Changing R9 and/or R11 and/or…

    Hi ADI team,

    Please help review our 5V to P/N12V power design base on ADP5070, Thanks!

  • ADP5070 Output Voltage issue(0V)

    Hi ADI Team,

    Please find the attached below schematic.

    Given Input Voltage:5V

    We are getting VREG-4.2V 

    EN1 and EN2 both goes up to 5V properly. but we are not getting the both Pos and Neg output Voltages,both are showing 0V.

    Is there some point to check…

  • ADP5070使用问题

    您好,项目中需要正负15V电源输出,然后使用了贵公司芯片ADP5070,,按照芯片手册中的推荐电路画了块PCB,唯一不同的是,我们的输入电压为15V,然后EN使能端我用了两个电阻分压使输入到En端电压为2.6V,AGND通过0ohm电阻接地,但是实际使用过程中,却没有任何电压输出,各个反馈电压也都没有,想知道是什么原因造成的。

  • RE: ADP5070输出异常

    请问解决了吗,我现在遇到了同样的问题,用5070转的正负15负,-15v带不了负载,带上负载直接变成-1.8v左右,vref输出为0,望大佬帮助一下

  • RE: ADP5070 sepic circuit sees overcurrent condition

    Sorry for long delay. It would be faster if you send me email. I can't exactly tell what's going on until you send me more waveforms including zoomed in version of several nodes. I would recommend that you use our ADIsimPower tool to generate the right…

  • ADISimPower for ADP5070 SEPIC

    Hi !

    I'm trying to create a +5V and -5V for a 12V source with an ADP5070 using ADISimPower,
    but the tool don't work on my PC.
    I get a visual Basic error, a little help would be appreciated.

  • 使用长线缆供电时ADP5070不能正常工作的问题

    我使用ADIsimPower设计了基于ADP5070AREZ的电路,输入12V,输出±15V,在使用直流稳压电源供电的情况下工作非常正常。但我在直流电源和ADP5070之间加入长线缆(大约三百米)后,ADP5070的输入端降为9V,电路板中出现啸叫,此时提高直流电源供电电压,使得ADP5070输入回到12V,啸叫消失,但芯片正负输出均为0。换回短线缆(20厘米)后工作恢复正常,请问这是为什么呢?

  • ADP5070 Inverting regulator not working

    Hello Guys :) 

    I've done some design for adc & opamp 

    schematics are below

    But positive rail goes properly , but negative rail only goes up to 0.9V and it doesn't switching.

    EN1 and EN2 both goes up to 5V properly.
