  • ADP1614 as a LED Driver

    Hi All,

    My customer investigating low cost LED driver IC.

    Is it possible to use ADP1614 as a LED Driver with its adjustable current limit function?

    If yes, can I obtain reference circuit for 5 white LEDs in series?

    Thank you for your support.

    Best…

  • RE: ADP1613 SEPIC design steps

    Hi sereza1981,

    Using the excel tool, the ADP1614 could be used but it can only provide up to 1.2A.

    You may also take a look at LT8357. LT8357 Datasheet and Product Info | Analog Devices. It should have an available model in LTpowerCAD.

  • RE: Problem with the ADP1613

    Probably you hit the overcurrent/short-circuit  protection,  as your switch current will be around this  that value.

    With Vout=15 @ 0.5A and Vin=5V and about 90% Efficiency assumption (Fig.1), you have about 1.2 * 15V*0.5A / (5V*0.9) ~ 2Ain. 
    Figure 16 shows…

  • RE: Problem with ADP1614ACPZ-R7 boost design

    Hi Fil, thank you very much for the answer.

    Zener and R32 are not mounted. I only mount components por Boost conversion for avoid possible external errors.

    I'm going to test these 3 nodes.

    Application is part of a new model of EV Charging Station…

  • RE: ADP1621 Sepic & Cuk Design Poor Efficiency

    Hi Otmar,

    It actually makes sense to increase the inductor value. You may want to check Sepic-Cuk designer tool in ADP161x similar boost controller series to help you optimize the parts selected.

  • 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…

  • ADP1613 high noise on output (400mVpp)

    Hello,

    I designing a power supply +5V and -/+15V with ADP1613 and ADP1614 (+/-15V) for ADAS3022 and DAC LTC2668 from Linear Technology. I use ADP1613 to generate 6.5V from 5V input, then I use LDO to get clean 5V for analog circuit. After doing measurements…
