MBI5152 - Macroblock

MBI5152 16-Channel PWM Constant Current LED Driver

MBI5152 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with selectable 16-bit / 14-bit color depth. MBI5152 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 fo.
