STMICROELECTRONICS STEVAL-ILL035V1 Multi channel LED Driver Board with Integrated Boost Controller based on LED7708 and STM32F103C6T6A
STMICROELECTRONICS
The STEVAL-ILL035V1 is a demo board based on LED7708 LED driver and STM32F103C6T6A microcontroller. The LED7708 is a 16 channels LED driver with boost controller and 4 wire serial interface. The purpose of this demonstration board is to provide an application example of a compact LED backlight driver using the LED7708 device. The output voltage required by the LED strings connected to the output channels is derived from a single input rail and continuously adjusted to minimize the voltage drop (and power dissipation) across them, despite an independent PWM duty cycle for each one. The brightness of each LED string is digitally controlled with 12bit or 16bit dimming resolution. The board has been designed as a demonstration of a solution for medium/large LCD panel backlight drivers, but is suitable for any application involving several LEDs assembled in strings. Wide DC input voltage from 10V to 28V 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 (daughter board) Core Chip: LED7708 Device Topology: Boost (Step Up) No. of Outputs: 16Outputs Output Current: 85mA Output Voltage: - Input Voltage Min: 10V Input Voltage Max: 28V Dimming Control Type: PWM Kit Contents: Demo Board LED7708 & STM32F103C6T6A Product Range: - SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
