STEVAL-ILL070V3 - LED Array Driver Evaluation Board by STMicroelectronics
The STEVAL-ILL070V3 from STMicroelectronics is a sophisticated evaluation board designed for driving LED arrays. This product integrates the advanced features of ST's LED1202 12-channel low quiescent current LED driver, making it an excellent choice for a wide range of lighting applications, particularly those requiring multiple LEDs to be driven with precision and efficiency.
The LED1202 driver on the STEVAL-ILL070V3 is capable of providing 12-bit PWM dimming resolution at a 20kHz dimming frequency, which ensures flicker-free operation and smooth dimming transitions. This high resolution makes the board suitable for applications that demand precise control over light intensity, such as architectural lighting, signage, and backlighting for LCD displays.
One of the key features of the STEVAL-ILL070V3 is its ability to operate with a power supply voltage ranging from 5.5V to 38V, which provides flexibility for various design requirements. Additionally, the board can manage an output current up to 85 mA per channel, which can be adjusted through external resistors, and supports both analog and digital dimming modes.
For ease of use, the STEVAL-ILL070V3 comes with a user-friendly GUI (Graphical User Interface) that can be used to configure the LED driver's settings via an I2C interface. This allows designers to quickly set up and test their LED configurations, speeding up the development process.
The board's design also includes an array of protection features such as LED open-circuit, short-circuit, thermal shutdown, and under-voltage lockout, ensuring the longevity and reliability of the application. These protective measures are critical in maintaining the performance of the LED array under various operating conditions.
Overall, the STEVAL-ILL070V3 is a powerful tool for engineers and designers looking to create advanced LED lighting solutions. Its combination of high-resolution dimming, flexible power supply options, and robust protection features make it a versatile and reliable choice for driving sophisticated LED arrays.
