STEVAL-ILL049V1
LED driver based on the LED6001

The STEVAL-ILL049V1 is an adapter board designed to provide an application example of compact LED driver using the new LED6001 chip. The board is equipped with a single-channel, constant-current LED driver operating with both boost and SEPIC topologies. The brightness of the LED string connected to its output can be controlled through a PWM signal (0%-100% dimming) or a control voltage (10:1 analog dimming). Open LED, feedback disconnection, LED over-current and output-to-ground short-circuit (SEPIC only) faults are detected and managed.

The board has been designed to provide a real-estate solution example for all the applications involving several LEDs arranged is a single string (e.g. off-grid street lighting, advertisement panels, signs, gaming, etc.).
