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!
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…
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。
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
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…
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.
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？
Dear Sir/Madam,
"ADP507x_Designer_Release.xlsm" references PRD1483-r3 for ADP5070/71 sepic, buck configuration.
"ADP507x_Designer_Release.xlsm" has some images of the board and gerbers.
Could I please get the gerbers for this board…
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.
Is there some point to…
