This document describes a product called LED7708, which is a 16-channel x 85mA LED driver with a boost controller and a 4-wire serial interface. It has a wide input voltage range, adaptive output voltage for high efficiency, and various protection functions. The LED7708 is suitable for TV and monitor backlight units for LCD panels and RGB/RGGB backlight solutions.
The LED7708 is a high-performance integrated circuit designed to drive multiple LEDs from a single low-voltage rail. It combines a boost controller section with sixteen current generators and a 4-wire serial interface. The boost controller features an adaptive output voltage for high efficiency and includes internal LDOs for gate and device supply. It supports switching frequencies between 250 kHz and 1 MHz and offers programmable overvoltage and overcurrent protection.
