STMicroelectronics STEVAL-ILL035V1 Demonstration Board
STMicroelectronics STEVAL-ILL035V1 Demonstration Board is designed to provide an application example of a compact LED backlight driver using the LED7708 device. The board is equipped with a 16-channel LED driver with an integrated boost controller (the LED7708), power section components, and an STM32 microcontroller to easily control all the features via a USB connection. The board has been designed as a demonstration of a solution for medium/large LCD panel backlight drivers, but it is suitable for any application involving several LEDs assembled in strings (e.g., advertisement panels, signs, gaming, etc.).
Features
- 10VDC to 28VDC wide input voltage range
- Integrated boost converter with adaptive output voltage for minimum power dissipation
- Up to 92% boost converter efficiency
- 16 channels with up to 85mA/ch current capability and independent PWM brightness control
- Up to 15 white LEDs per channel
- On-board STM32 microcontroller for total device control through 4-wire serial interface
- Embedded open-channel and LED short-circuit faults management
- USB connection for device control through dedicated PC-GUI
- Expansion connector to support slave devices (daughterboard)
- RoHS compliant
