Additional Infomation About Product

LED7707 6-rows 85 mA LEDs driver with boost regulator for LCD panels backlight Datasheet - production data Applications LCD monitors and TV panels PDAs panel backlight GPS panel backlight Description VFQFPN-24 4x4 The LED7707 consists of a high efficiency Features monolithic boost converter and six controlled current generators (rows) specifically designed to Boost section supply LED arrays used in the backlighting of 4.5 V to 36 V input voltage range LCD panels. The device can manage an output Internal power MOSFET voltage up to 36 V (i.e. 10 white LEDs per row). Internal +5 V LDO for device supply The generators can be externally programmed to Up to 36 V output voltage sink up to 85 mA and can be dimmed via a PWM Constant frequency peak current-mode signal (1% dimming duty-cycle at 1 kHz can be control managed). The device can detect and manage open circuit and short-circuit LED faults and leave 250 kHz to 1 MHz adjustable switching unused rows floating. Basic protections (output frequency overvoltage, internal MOSFET overcurrent and External synchronization for multi-device thermal shutdown) are provided. application Pulse-skip power saving mode at light load Programmable soft-start Programmable OVP protection Stable with ceramic output capacitors Thermal shutdown Backlight driver section Six rows with 85 mA maximum current capability (adjustable) Rows disable option Less than 10 s minimum dimming on-time 2% current matching between rows LED failure (open and short-circuit) detection Table 1.
