  • The purpose of this evaluation board is to provide an application example of a six-channel, medium-current LED driver using the ALED7707 chip. The monolithic boost converter provides the required LED supply voltage starting from a single supply rail, while the brightness of the LED strings connected to the six outputs is controlled through a PWM signal. Open LED and LED short-circuit fault conditions are detected and managed.

    The board has been designed to provide a compact reference solution for automotive applications involving several LEDs arranged in multiple strings (e.g. interior lighting, infotainment LCD backlighting, etc.).

    Key Features

    • Wide DC input voltage (6 V - 32 V)
    • Six 70 mA output channels (capable of 30 mA to 85 mA each)
    • PWM brightness control (10 µs minimum dimming on-time)
    • Up to 10 white LEDs per channel (36 V OVP threshold)
    • > 90% efficiency (VIN=12 V, VBOOST=30 V, fSW=1 MHz, no snubber)
    • On-board input filter for conducted EMI reduction
    • RoHS compliant
    • All automotive-grade components
