Description
The purpose of this product evaluation board is to provide 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 has 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.).
