Evaluation Board for LED7706
This board is based on the LED7706 and implements a high-efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LEDs arrays used in the backlight of LCD panels.
Input voltage range: +4.5 to +36V
Internal power MOSFET
Internal +5V LDO for device supply
Up to 36V output voltage
Constant frequency peak current-mode control
200kHz to 1MHz adjustable switching frequency
External sync for multi-device application
Pulse-skip power saving mode at light load
Programmable soft-start
Programmable OVP protection
Single ceramic output capacitor
Non-latched thermal shutdown
Six rows with 30mA maximum current capability (adjustable)
Up to 10 white LEDs per row
Row disable option
Less than 500ns minimum dimming time (1% minimum dimming duty-cycle at 20kHz dimming frequency)
±2.0% current matching between rows
LED failure (open and short circuit) detection
