Description:

 MBI5030 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with 12-bit gray scales. MBI5031 features a 16-bit shift register which converts serial input data into each 12-bit pixel gray scale of output port. At MBI5031 output port, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs with a wide range of Vf variations. The output current can be preset through an external resistor. Moreover, the preset current of MBI5031 can be further programmed up or down to 128 gain steps for LED global brightness adjustment.

With Scrambled-PWM (S-PWM^TM) technology, MBI5031 enhances Pulse Width Modulation by scrambling the “on” time into several “on” periods. The enhancement equivalently increases the visual refresh rate. When building a 12-bit gray scale video, S-PWM™ reduces the flickers and improves the fidelity. MBI5031 offloads the signal timing generation of the host controller which just needs to feed data into drivers. MBI5031 drives the corresponding LEDs to the brightness specified by image data. With MBI5031, all output channels can be built with 12-bit color depths (4,096 gray scales).
