MBI5031 - Macroblock

MBI5031 16-Channel Constant Current LED Driver

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 sin.
