4 ch Current Driver Integrated, Built-in MOS for Boost, Boost DC/DC Converter

White LED Driver for Automotive

BD83A04EFV-M

General Description

Key Specifications

This IC is a white LED driver for LCD backlight.

It has MOS for boost and 4 ch 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

medium 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 boost applications, and the

input operating voltage range is 4.5 V to 48 V.
