LP5569: 1.8V pin

Part Number: LP5569

Tool/software:

I'm planning on using LP5569 without ChagePump.
Do I have to connect 1.8V to the device? I want to use it but don't want to add LDO only for the LED driver.


Thanks in advanced

  • Hi Ofer,

    Yes, you need to connect 1.8V to the device since it's power for internal digital part.

    If you don't want to use a LDO for the 1.8V input, I will recommend you to use the next gen of LP5569, LP5813.

    BR, Jared
