MBI5050 features a 16-bit shift register which converts serial input data into each pixel’s gray scale of the 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 MBI5050 can be further programmed to 64-step for LED global brightness adjustment. The innovative arch...
