BD83A14EFV-M BD83A14MUF-M White LED Driver for Automotive 4 ch Current Driver Integrated, Built-in MOS for Boost DC/DC Controller Datasheet

2023-09-27
●General Description
■This IC is a white LED driver for LCD backlight.
■It has 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 48.0 V.
