• RE: ADAS3022 Recommended Circuit Help

    Hi codigwe,

    Seems you follow the recommended setting for the reference circuit.It should be able to power the ADR435 with a  +15V supply. . Aside from ADAS3022 and ADR435 what other components connected to this? it draw current if the total impedance excess…

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

    John,

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

  • RE: Dual-supply design from phantom power

    Jerad and I had some off line discussions and the solutions was narrowed to use a 9V battery and generate a regulated +/-9V supply with an additional 3.3V.

     

    For the +/-9V:

    You can use the Coupled SEPIC cuk topology to develop the +/-9V (adjustable…

  • 微信上的一条爆款文章——如何设计滤波器堵住开关电源的噪声

    版主逛公众号时,看到射频人气账号“射频百花潭”发布了一篇咱们的技术文章,反响很不错,版主就搬到这里分享下,顺表再附上一些相关资料,供大家参考学习~

    开关电源几乎用于所有电子设备中。它们由于尺寸小、成本低和效率高而具有极高的价值,但是,它们最大的缺点就是高开关瞬态导致高输出噪声。这个缺点使它们无法用于以线性稳压器供电为主的高性能模拟电路中。

    实践证明,在很多应用中,经过适当滤波的开关转换器可以代替线性稳压器从而产生低噪声电源。哪怕在要求极低噪声电源的苛刻应用中,上游电源树的某个地方也有可能存在开关电路…

  • RE: Boost Circuit Design - ADP1621 suitable?

    Hello,

    So it appears you have downloaded some of our design tools.  As you will notice at the top of the ADP1621 boost designer the schematic is labeled "Complete Schematic for Demo Board;"  You need to look at the BOM located below the scehmatic…

  • RE: ADM8845 backlight LED driver consumes too much current

    Ok, I think I understand the issue now.  Actually there are 2 problems:

    1.  Since you're operating right at the point of the gain change (3.33V), you could be in either 1.5x mode or 2x mode.  If Vin does not have enough cap on it, then when you change…
