MBI5168 exploits PrecisionDrive™ technology to enhance its output characteristics. MBI5168 contains a serial buffer and data latches, which convert serial input data into parallel output format. At MBI5168 output stage, eight regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf variations. The excellent output accuracy is within ±3% between channels and within ±6% between ICs. Users may adjust the output current from 5 mA to 120 mA through an external resistor Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI5168 guarantees to endure maximum 17V at the output ports. The high clock frequency up to 25 MHz also satisfies the system requirements of high volume data transmission
