• RE: ADP1613, inrush current at inductor

    Hi Hong,

    Thank you very much for your kind reply. We can try the way using precharged cout.

    In addition, I saw ADP1614 datasheet and know it is resemble to ADP1613 and doesn't show inrush current at inductor such ADP1613 shows, however not pin-compatible…

  • RE: ADP1613 current drive

    Hi Ajith,

     

    The ADP1613 can NOT support 5V in 5.9V @2A out due to the current limit of the IC. The option is using ADP1614 instead of ADP1613. And the ADP1614 has smaller size ( 9mm^2 10-lead LFCSP) compared to the ADP1613 (14.7mm^2  8-lead MSOP). 

  • RE: 3V to 20V Boost for Low Current Application

    John,

    a boost regulator like the ADP1613 or ADP1614 will do the job.

  • 关于ADP1613生成正负10V的问题

    我按照ADP1613手册上的参考电路绘制了一个生成正负10V的电路,但是在实际测试中发现,生成的正电压能达到9.85V左右,但负的电压只能达到-7.5V。下面分别是我参考的手册上的电路与自己画的电路

    红框内是我参考的电路。

    下面是我画的电路

    请问电路里是有什么地方出现问题了吗。

    急需解答,谢谢大家的帮助!

  • RE: AD5721R Circuit Implementation Questions

    Hi,

    Item 1. If you need 16V output from 3.3V input, ADP1613 is ok. You may want to do 17V output at ADP1613 and then to an ADP7142 to get 16V.  LDO is recommended for better noise performance.
    Note: The datasheet actually only recommends only 1 ADP5070…

  • RE: Can you show me how to make an ADP1613 spice model?

    Hello!

    Sorry but we do not have any SPICE model for ADP1613.

    May I know what you need from the model or simulation?

    Alternatively, you may download any of the design tools available for ADP1613, and here they are:

  • ADP1613 and ADM7150 layout suggestions

    Hello, 

    I'm designing a power supply for data acquisition device which needs clean 5V. I decided to use ADP1613 and ADM7150 ICs to get 6.2V from SEPIC DC/DC converter and 5V from LDO. Power requirement is 5V@200mA and less then 1mV ripple. I want to…

  • ADP1613 SEPIC - spikes on output

    I am using an ADP1613 in a SEPIC configuration to convert either a 3.6V battery or a 9V power input into a 5V output. I used the ADP161x SEPIC designer to get the correct component values. A power path circuit chooses the 9V if present or the 3.6V if…
