MBI6353 is an advanced 48-channel high power constant current full-array local dimming (FALD) backlighting LED driver for large-mid LCD panel applications. The innovative architecture is designed to support up to 1:4 time-multiplexing and control up to 192 LED dimming zones application using internal Pulse Width Modulation Dimming(P-DIM) and Analog Dimming(A-DIM) control with 12-bit color depth and extra 2-bits high luminance mode by zone to improve contrast ratio for HDR applications.
Both compulsory and real-time LED error open/short detection and protection are included during both start-up and normal operation. Besides, MBI6353 also provides DC/DC feedback control, ghost elimination function and over temperature protection features.
