  • This demonstration board is based on the LED7706 and implements a high efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LEDs arrays used in the backlight of LCD panels.

    The device can manage an output voltage up to 36 V (i.e. ten white-LEDs per row).
    The generators can be externally programmed to sink up to 30 mA and can be dimmed via a PWM signal (1% dimming duty cycle at 20 kHz can be managed).
    The device allows to detect and manage the open and shorted LED faults and to let unused rows floating.
    Basic protections (output overvoltage, internal MOSFET overcurrent and thermal shutdown) are provided.
