Product Description
MBI5031 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with 12-bit color depth. MBI5031 features a 16-bit shift register which converts serial input data into each pixel 12bits 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...
