• ADP5071 SEPIC + Inverter Mode Layout

    Dear ADI,

    Do you have a reference layout for the ADP5071 in SEPIC Mode on Ch1 and Inverter Output on Ch2, like shown on page 25 of the datasheet?

    Thank you!

    Regards,

  • ADP5071 can't start when load large capacitors.

    Hello everyone,

         As specified in the datasheet, ADP5071 will shutdown if the current exceed the limit. When I use about 100uF capacitor, the start curve is as follow.

         But if I keep increaing the capacitor, it will never work normal. So how can we…

  • How to connect two ADP5071 regulators in parallel?

    Hi,

    I have designed a regulator circuit with ADP5071 for 1A load but I need 1.6A load. In board I have two ADP5071 regulators. Both the regulator outputs are 5V and one has 1.4A load and other has 0.2A load.

    1. Is it OK, if I connect both the regulator…

  • adp5071带负载之后烧坏

    最近按照ADP5071评估板的电路自己画了一块,ADP7142和ADP7182并未焊接上。首先对ADP5071进行测试,输入电压为12V,输出正负13.5V。电感值是按照评估板上的,正向3.3uH,反向6.8uH。空载时电压输出正常。分别在正负电源的输出端加载一个100欧姆的水泥电阻。对应的正电源的负载电流为135mA,负电源的负载电流也为135mA。上电开始时电压输出正常,过30秒-60秒后突然没有电压输出了,然后芯片就烧坏了。这是什么原因呢?

  • ADP5071的电阻选择问题

    我对ADP5071的电阻使用问题不是很清楚。

    输入12V,输出正负15V;我看了手册基本上只需要修改Rc1、L1、Rc2、L2的值就行了,可以告诉我怎么计算这些值吗?给出例子可以吗

  • Is a disabled ADP5071 safe against reverse currents?

    Hi,

    I have a ADP5071 that is used for a +/-15 V supply. For some tests I would like to disable the ADP5071 by pulling the EN low, and supply the +/-15 V from an external source.

    Is it safe to do so, or would horrible things happen because of reverse…

  • With regards to FB resistor on ADP5071

    Hi ,

    The Feed back resistor given by the Sim Power and the recommended values Table 8. differ greatly. One on SimPower is in order of 10ks and one on Table is Mega ohms .

    Both seems to clear the criteria of 10 time the Ifb .

    Please let me know with…

  • ADP5071 EMI suppression in Radiative Emission certification test

    Hello

    I've recently developed a power board for a frontend data acquisition system, in which I've the ADP5071 to provide the +/-5V for opamp circuitry. 

    I've used the recommended schematics and board layout described in the datasheet, however during…

  • ADP5071 2 A/1.2 A How to achieve

    hi,I use Input power 5V4A,want to get ±6V,1.5A,but I use ADP507x_DesignerTools,Remind me the maximum current is 1.25and.37,What am i doing wrong?

  • How to handle the pins related negative output on ADP5071?

    Hi,

    My customer use ADP5071 and would like to know how to handle VREF, COMP2, FB2 and SW2 if they don't need negative output ?
