STMicroelectronics LED7708 | Demoboard STEVAL-ILL035V1
Multi-channel LED driver with integrated boost controller for medium, large LCD panel backlight based on LED7708 and STM32F103C6T6A
Overview
| Topology | Boost Converter |
| Input voltage | 10-28 V |
| IC revision | 1 |
Description
The purpose of the STEVAL-ILL035V1demonstration board is to provide an application example of a compact LED backlight driver using the LED7708 device.The board is equipped with a 16-channel LEDdriver with integrated boost controller (theLED7708), power section components, and anSTM32 microcontroller to easily control all thefeatures via a USB connection.The output voltage required by the LED stringsconnected 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 12- or 16-bit dimming resolution.Embedded, programmable fault detection andmanagement circuitry can be set to automatically disconnect faulty channels without the need for intervention by the host controller.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 (e.g. advertisement panels, signs, gaming, etc.).
Features
- Wide DC input voltage: 10 V to 28 V
- Integrated boost converter with adaptive output voltage for minimum power dissipation
- Up to 92% boost converter efficiency
- 16 channels with up to 85 mA/ch currentcapability and independent PWM brightnesscontrol
- Up to 15 white LEDs per channel
- On-board STM32 microcontroller for totaldevice control through 4-wire serial interface
- Embedded open-channel and LED short-circuit faults management
- USB connection for device control throughdedicated PC-GUI
- Expansion connector to support slave devices(daughterboard)
- RoHS compliant
