Product Summary

The mbi5040gf is an 8 bit constant current led driver. The mbi5040gf is targeted for LED panel display. The mbi5040gf contains CMOS shift registers and latch functions converting serial input data into parallel output format. At the output stage, eight regulated current sources were designed to provide 5-90 mA constant current for driving LEDs. The mbi5040gf provides users with great flexibility and device performance while using the mbi5040gf in their LED panel system design. Users may adjust the output current of the mbi5040gf through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. The mbi5040gf guarantees to endure maximum 17V at the output port, allowing users to connect more LEDs in series. The high clock frequency, 20 MHz, also satisfies the system requirement of high volume data transmission.
