MBI5028 - Macroblock

MBI5028 16-bit Constant Current LED Sink Driver

MBI5028 succeeds MBI5026 and is designed for LED displays with Gain Control extension. MBI5028 exploits PrecisionDrive™ technology to enhance its output characteristics. MBI5028 contains a serial buffer and data latches, which convert serial input data into parallel output format. At MBI5028 output stage, sixteen regulated current ports are designed to provi.
