BFP SYSTEM :

Quick Starting Guide

If you need to use very low current, < 100 mA, we recommend to set LED driver in low-power mode.

There is a minimum current threshold of 40 mA in normal mode, and 4 mA in low power mode. Below
this value, LED will turn OFF completely.

4.3. BFP Set New Configuration

(Configuration Tab)

In the BFP Driver tab, go to Configuration tab, and click + NEW/EDIT button.
