LP5569: 1.8V pin

Ofer Gal

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
