MBI6312 is an advanced 12-channel high power constant current full array local dimming (FALD) backlight LED driver for mid-sized LCD panel applications. This innovative architecture is designed to support BCON-less static LED dimming applications. It uses internal pulse-width modulation dimming (P-DIM) with 12-bit color depth and analog dimming (A-DIM) with 10-bit color depth to achieve better PQ. Another new technology is the special data transmission design, which can achieve the lowest latency display effects.
Includes real-time LED false open/short detection and protection during startup and normal operation. In addition, MBI6312 also provides DC/DC feedback control, ghost elimination function, and over-temperature protection function.
