Other Parts Discussed in Thread: LP5569

Dear team

The customer has a new project that will use 8 red light LEDs and need to have the function of breathing light.
Please provide suggestions for connecting LED drivers in series or parallel for reference, thank you.

The current of LED is about 10mA, If the LP5562 can support 8 red LED in series or 4 series and two parallel?

Many thanks

Denny

    Hi Denny, 
    

    I don't recommend connecting multiple LEDs in series with LP5562 because the Max VDD=5.5V is sometimes insufficient. 9-channel LP5569 can be a better candidate in this case. If you have any concerns, feel free to contact me or visit the Quick Search (hyperlinked) to filter out other suitable devices. 
    

    Best Regards, 
    

    Aaron Bing
