Hi Hemry,

What is the LED string voltage? And seems the LED string current is 2*8=16mA, but currently you set the current as 20mA with 10ohm resistor.

Hi Hemry,

It is ok to use TPS61169, but please be noted that the total current is 20mA, but IC cannot guarantee each string will have 10mA. The uniformity is related to LED string itself.
