          描述 Description

          The LED7707 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 36 V (i.e. 10 white LEDs per row).

          The generators can be externally programmed to sink up to 85 mA and can be dimmed via a PWM signal (1% dimming duty-cycle at 1 kHz can be managed). The device can detect and manage open circuit and short-circuit LED faults and to leave unused rows floating. Basic protections (output overvoltage, internal MOSFET overcurrent and thermal shutdown) are provided.
