• ADP5070 unused output

    Hi,

    Because of difficulties to order ADP5075 I think about using the ADP5070/1 for generating a single negative supply in my design. I am using the device for two different voltages, so I thought I could close the gap with the same device.

    If I use only…

  • RE: ADP5070 has no negative voltage

    Hello AndreiF, well finally the fault was easy. Now my design works. The goal has nothing to do with simulation or other "ideas" behind any tools. The solution for me was, that I did not resprect the given table on page 23 showing the needed values for…

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

  • ADP5070/5071 Loop compensation component selection (disparity between datasheet & ADIsimPower)

    Hi,

    I'm trying to optimize the compensation RC values for our design. I notice the recommended values in the datasheet (Table 10 & Table 11) are vastly different than the recommended value in ADIsimPower. For example below are the recommendations for…

  • 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。

  • 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…

  • 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

  • ADP5070 sepic circuit sees overcurrent condition

    Hi guys,
    I'M using a ADP5070 from analog device to generate a +8V and a -4V . The circuit for the -4V works fine. As for the +8V it does not.
    The circuit used is a SEPIC topology. You can see the circuit schematic in the pictures linked(sepic.png).

  • 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?
