LED7707

LED DRIVER, 6X0.085A, 1MHZ, 24VFQFPN.

The LED7707 is a 6-row LED Driver with boost regulator. It consists of a high efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LEDs arrays used in the backlighting of LCD panels. The device can manage an output voltage up to 36V (10 white LEDs per row). The generators can be externally programmed to sink up to 85mA and can be dimmed via a PWM signal (1% dimming duty-cycle at 1kHz 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 over-voltage, internal MOSFET overcurrent and thermal shutdown) are provided.
