Macroblock, Inc. MBI5016 16-bit Constant Current LED Sink Driver April 2002 Features MBI5016CNS * 16 constant current output channels * adjustable output current through external resistor * serial data in/parallel data out * output current: 5-90 mA * 20MHZ clock freq. MBI5016CF Product Description The MBI5016, utilizing the most advanced Si technology, is targeted for LED panel display. The MBI5016 contains CMOS shift registers and latch functions, converting serial input data into parallel output format. At output stage, sixteen regulated current sources were designed to provide 5-90 mA constant current for driving the LEDs MBI5016CP The MBI5016 provides users great flexibility and device performance while using the MBI5016 in their LED panel system design. Users may adjust the output current of the MBI5016 through an external resistor R-ext., which gives users flexibility in controlling the light intensity of LEDs . The MBI5016 guarantees 17V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 20 MHz, also satisfies the system requirement of high volume data transmission.
