Features

■

Description

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).
