Design & Manufacture
Available now from Mouser stock, the STEVAL-ILL049V12 evaluation board
provides an application example of a compact LED driver using the new
LED6001 chip from STMicroelectronics.
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 overcurrent and output-to-ground short-circuit
(SEPIC only) faults are detected and managed.
The board is been designed to provide a solution example for applications
involving several LEDs arranged is a single string (e.g. off-grid street
lighting, advertisement panels, signs, gaming, etc.).
