DESCRIPTION
MBI5153 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with selectable 14-bit / 13-bit color depth. MBI5153 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.
