Description

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.
Internal power MOSFET
Internal +5V LDO for device supply
Constant frequency peak current-mode control
External synchronization for multi-device application
Pulse-skip power saving mode at light load
Programmable soft-start
Programmable OVP protection
Stable with ceramic output capacitors
Thermal shutdown
250kHz to 1MHz Adjustable switching frequency
Backlight driver - <10µs Minimum dimming on-time and ±2% current matching between rows
