Product Description
STMicroelectronics STEVAL-ILL067V1 LED Driver Evaluation Board utilizes the ALED7707 six-channel medium-current LED driver IC designed for applications requiring precise LED brightness control with high efficiency. The monolithic boost converter topology enables the supply voltage to the LEDs from a single power rail, facilitating ease of implementation in various systems. The evaluation board supports a wide DC input voltage ranging from 6 V to 32 V, suitable for automotive and industrial environments.
The device features six output channels capable of driving currents from 30 mA to 85 mA with a nominal current of 70 mA per channel. Brightness control is managed through PWM signals with a minimum dimming on-time of 10 microseconds, providing fine control over LED intensity. Each output channel can drive up to 10 white LEDs, protected against overvoltage conditions up to 36 V.
Efficiency exceeds 90% at 12 V input voltage, 30 V boost voltage, and a 1 MHz switching frequency without a snubber, highlighting its suitability for energy-conscious applications. An on-board input filter significantly reduces conducted electromagnetic interference, enhancing system robustness.
The board monitors open LED and LED short-circuit faults, offering reliable fault detection and management. This compact evaluation kit serves as a practical reference design for automotive interior lighting, infotainment LCD backlighting, and other multi-string LED lighting systems.
STMicroelectronics ensures quality with design and manufacturing in Italy, complying with RoHS standards.
Ideal for industrial, automotive, and commercial electronics development, the STEVAL-ILL067V1 aids engineers in prototyping and validating LED driver circuits. Its robust design and comprehensive features make it an essential tool for tackling medium-current LED driving challenges with ease and precision.
