General Description

MBI5368 is designed for fine pitch LED display applications and exploits PrecisionDrive™ technology to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.

In one package, MBI5368 incorporate three 8-channel drivers that output current can be adjusted through three external resistors and moreover be programmable to 256 gain steps for LED white balance MBI5368 provides users with great flexibility and small package while using surface mounted RGB LEDs to display precisely video color.

Users may adjust the output current from 10 mA to 60 mA through separately external resistor Rext and 8-bit current gain control, which gives users flexibility in the color correction of LEDs.
