Update: 30 September, 2023
The LED7707 LED driver is a high-efficiency monolithic boost converter and six controlled current generators (rows), specifically designed to supply LED arrays used in the backlighting 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 85 mA and can be dimmed via a PWM signal (1% of minimum dimming duty-cycle at 1 kHz can be managed). The device allows detection and management of open and shorted LED faults, and permits unused rows to be left floating. Basic protections (output overvoltage, internal MOSFET overcurrent and thermal shutdown) are provided.
