• ADD5211

    Hi,

    Page one of the ADD5211 data sheet states that PWM dimming at 300 Hz, what is the maximum frequency that can be used for PWM dimming?

    Best Regards.

  • Motion when power-on at -40C for ADD5211


    Dear Sir/Madam,

    I got one question from our customer.

    As for ADD5211 that was storaged on -40C, if we power supply it, then what trouble has comin?

    Not wake-up?

    Wake-up but not drive internal FET?

    Please let me know your expected result for this…

  • ADD5211 power on

    Dear Sir/Madam,

    I`m using the ADD5211 to drive a LCD backlight, but sometimes (very rare) it doesn´t power on.

    After connecting the EN-pin or the UVLO-pin shortly to ground it starts again.

    Unfortunately I didn´t connect the Fault-pin, so I can`t monitor…

  • RE: Consumption current of ADD5211

    Hi Kaos,

    Yes, you can approximate the amount of power that the ADD5211 can dissipate by following the instructions in this thread:

    Using of 2 ganged FBs ADD5211

    It is just an approximation though, and so you should use it conservatively.   Theta JC is…

  • ADD5211 Cout,inductor scream issue

    Good day,

             We use ADD5211  for four-string LED driving, input voltage is 12v, output voltage is 20.4v/89mA per string.

    All parameters follow the datasheet and tool guidance, ADD5211 can delight the LEDs but scream issue happen with Cin, Cout and boost…

  • ADD5211驱动led有是线性调光，无闪烁的吗？

    想用于高速机器视觉，控制曝光时间较短，想确认无闪烁的LED数字调光方案，如果这个不能用，请推荐个符合要求的，我的LED阵列每个灯最大电流20mA以上，至于串的数量没有要求，我可以多加几个芯片来实现整个阵的点亮，谢谢！！
