The purpose of the STEVAL-ILL039V2 demonstration board is to provide an example for applications of an LED driver using the step-up controller STLDC08.
The STLDC08 is designed for handheld equipment supplied by AA or AAA batteries and provides a precise constant current starting from a variable input voltage source.
The LED current is set by an external sense resistor inserted between the feedback pin (FB) and GND.
A regulation loop holds the voltage drop at the sense resistor at a constant level (typ. 100 mV).
