General Description

This IC is a white LED driver for LCD backlight.

It has 6ch current drivers for LED drive, making it ideal for

high brightness LED drive. LED pin maximum voltage is

50 V, making it suitable for driving large LCD panels.

The dimming is controlled by the PWM signal and can be

set up to 20,000: 1@100 Hz. It also supports analog

dimming, and can accommodate even higher brightness

ranges by combining with PWM dimming. DC/DC

converters can be controlled for BuckBoost applications,

and the input operating voltage range is 3.0 V to 48 V.
