STMicroelectronics 3 A LED Driver Evaluation Board for LED5000 STEVAL-ILL063V1

STMicroelectronics STEVAL-ILL063V1 is a 3 A LED Driver Evaluation Board designed around the LED5000 device, a step-down current source with dimming capability, suitable for high-precision LED lighting applications. It delivers an adjustable output current with a maximum of 3A DC, set by a sensing resistor on the feedback pin to regulate current precisely.

The board operates within a broad input voltage range of 5.5V to 48V, featuring a fixed switching frequency of 850kHz that ensures efficient power conversion and stable output. The floating boost topology supports optimal LED driver performance and is compliant with ceramic output capacitors, enhancing system reliability and minimizing electromagnetic interference.

Built-in protections include safeguards against overheating, over-current conditions, and output short-circuits, ensuring robust and durable operation in industrial, commercial, and architectural LED lighting systems. The device also supports PWM dimming for variable brightness control and maintains a tight ±3% output current accuracy across temperature variations.

The current sense voltage drop is typically 200mV, optimized by the sensing resistor on the feedback pin. Additional features include an inhibit function that enables zero current consumption and a thermal shutdown to protect electronic components during fault conditions.

This evaluation board is ideal for engineers and designers working on LED lighting designs requiring efficient, precise current regulation and robust protection features. It serves applications in industrial lighting, architectural illumination, automotive lighting development, and laboratory prototyping.
