• ADP8866 draws too much current at boot-up

    I'm trying to boot-up the ADP8866 LED driver on a protoboard following the typical operating circuit (1 uF C1, 1 uF C2, 1 uF Cin, 1 uF Cout) without luck.

    With a power supply Vin=3.3V, the current fluctuates between 5mA and 30mA until it reaches 50mA…

  • RE: ADP8866 - change brightness level of BL during fade-out transition

    Hi Dave,

    sorry for my late response. Thanks for your hint, it is working! Unfortunately not as expected or needed.

    When I turn on all LEDs (8) configured as BL and immediately (from my perspective) turn off all LEDs, the behavior is unexpected - LEDs…

  • ADP8866 Output Current for each LED channel


    I am trying to match the current I observe the ADP8866 draw versus the expected current (obtained from Register Settings). There are 8 LEDs total connected to the ADP8866. 2 Blue LEDs(D1,D2: Part Number:SMS1105BWC) and 6 white LEDs (D3 to D8, Part Number…

  • RE: EVAL-ADP8866

    I see this is an old post, but I'd like to add some helpful info to it:

    The ADP8866 eval board software only communicates with the hardware on Windows XP and previous.  It doesn't work on Win 7/10, etc.  Therefore, we made the decision to stop…

  • ADP8866 Interface Example

    The datasheet for the ADP8866 is very clear on part internal registers and how to read/write from them. What is missing is simple direction on which specific registers to read/write to turn on or off an LED. Usually, with parts like the ADP8866, the challenge…

  • ADP8866评估板 没有相关说明资料

    有设计可能用到LED驱动芯片ADP8866,想看一下ADP8866评估板 是否可以直接拿来使用,可是在网站找不到相关资料,能否提供参考资料(使用手册或介绍)?谢谢!

  • RE: A couple of questions for your ADD5211 LED driver

    Hi Kaos,

    No, the minimum is 15mA.  For lower current, I would suggest the ADD5203, ADP8870 (or ADP8866), or the ADP8140.  The ADP8140 has the best DC dimming and DC dimming range. 

    Best Regards,
